Time-resolved measurements reveal rotational dynamics much slower than that of isolated molecules and absence of the sharp transient alignment recurrences characteristic of gas phase molecules. Our results presage a range of new opportunities for exploring both molecular dynamics in a dissipative environment and the properties of He nanodroplets.

Electronic spectra of 9,10-dichloroanthracene in helium droplets are presented and compared with corresponding gas phase spectra to unravel the influence of the helium environment. The combined investigation of fluorescence excitation and dispersed emission provides information on dynamic processes in addition to energetic conditions. For vibronic states, the helium induced decay channels dominate over all intramolecular channels that contribute to the gas phase behavior. In addition to the triplet splitting caused by the Cl isotopes, a fine structure resolved for all transitions in the fluorescence excitation spectrum was found, which is the signature of microsolvation of this compound in helium droplets. This fine structure is identified as a single pure molecular transition accompanied by a sharply structured phonon wing. The corresponding fine structure measured for bare anthracene shows remarkable differences.

Among the polyacene molecules benzene, naphthalene, anthracene, tetracene and pentacene only anthracene and tetracene have been found to exhibit multiplet splitting of the electronic and vibronic transitions which can not be explained by a rotational fine structure. The experimental approach for the investigation of the multiplet is the combined investigation of the fluorescence excitation spectrum and dispersed emission spectra. New experimental data are presented on the microsolvation of anthracene in helium droplets. A detailed analysis of the anthracene data will be contrasted to corresponding data on tetracene. These data together with those reported for benzene, naphthalene and pentacene might serve to test and develop theoretical models which are needed to understand microsolvation of single molecules in superfluid helium droplets.

T1 - Electronic spectroscopy of molecules in superfluid helium nanodroplets: an excellent sensor for intramolecular charge redistribution JF - The Journal of Physical Chemistry, Special Issue: J. Peter Toennies Festschrift N2 - Electronic spectra of molecules doped into superfluid 4He nanodroplets reveal important details of the microsolvation in superfluid helium. The vibrational fine structure in the electronic spectra of phthalocyanine derivatives and pyrromethene dye molecules doped into superfluid helium droplets have been investigated. Together with previous studies on anthracene derivatives [J. Chem. Phys.2010, 133, 114505] and 3-hydroxyflavone [J. Chem. Phys.2009, 131, 194307], the line shapes vary between two limiting cases, namely, sharp Lorentzians and nonresolved vibrational fine structure. All different spectral signatures are initiated by the same effect, namely, the change of the electron density distribution initiated by the electronic excitation. This change can be quantified by the difference of the electrostatic moments of the molecule in the electronic ground state and the corresponding Franck–Condon point in the excited state. According to the experimental data, electronic spectroscopy suffers from drastic line broadening when accompanied by significant changes of the charge distribution, in particular, changes of the dipole moment. Vice versa, the vibrational fine structure in electronic spectra of molecules doped into helium droplets is highly sensitive to changes of the electron density distribution.

T1 - High-resolution electronic spectroscopy of the BODIPY chromophore in supersonic beam and superfluid helium droplets JF - CHEM-PHYS-CHEM, Special Issue: Laser Chemistry and Spectroscopy N2 - We present the fluorescence excitation and dispersed emission spectra of the parent compound of the boron dipyrromethene (BODIPY) dye class measured in a supersonic beam and isolated in superfluid helium nanodroplets. The gas‐phase spectrum of the isolated molecules displays many low‐frequency transitions that are assigned to a symmetry‐breaking mode with a strongly nonharmonic potential, presumably the out‐of‐plane wagging mode of the BF2 group. The data are in good agreement with transition energies and Franck–Condon factors calculated for a double minimum potential in the upper electronic state. The corresponding transitions do not appear in the helium droplet. This is explained with the quasi‐rigid first layer of helium atoms attached to the dopant molecule by van der Waals forces. The spectral characteristics are those of a cyanine dye rather than that of an aromatic chromophore.

A1 - Slenczka, Alkwin T1 - Line broadening in electronic spectra of anthracene derivatives inside superfluid helium nanodroplets JF - The Journal of Chemical Physics N2 - Electronic spectroscopy of molecules profits greatly from superfluid helium droplets serving as a gentle cryogenic matrix. Characteristic features of electronic spectra in helium droplets are a solvent shift, phonon wings, and in rare cases a splitting of zero phonon lines. For the majority of molecules investigated so far in helium droplets the vibrational fine structure in electronic spectra resembles what was observed in a supersonic jet. The electronic spectra of three methylated anthracene derivatives and one phenylated anthracene discussed in this paper reveal remarkable effects in the vibrational fine structure due to solvation in helium droplets. For all four compounds the vibrational frequencies were almost not affected by the helium environment. However, if the electronic excitation is accompanied by nuclear rearrangement, the spectra showed remarkable line broadening in helium droplets. This is the case for 2-methylanthracene and 9-phenylanthracene. The corresponding line shape was of Lorentzian type and, thus, attributed to damping of the excited system by the helium environment. According to the linewidth the damping time constant was determined to be about 0.3 ps in the case of 2-methylanthracene and 0.1 ps for 9-phenylanthracene.

It was intensively studied for the bare molecule and for the influence of solvents. In the present paper this photocycle is investigated for 3-hydroxyflavone and some hydrated complexes when doped into superfluid helium droplets by the combined measurement of fluorescence excitation spectra and dispersed emission spectra. Significant discrepancies in the proton transfer behavior to gas phase experiments provide evidence for the presence of different complex configurations of the hydrated complexes in helium droplets. Moreover, for bare 3-hydroxyflavone and its hydrated complexes the proton transfer appears to be promoted by the helium environment.

T1 - Rapidly pulsed helium droplet source JF - Review of scientific instruments N2 - A pulsed valve connected to a closed-cycle cryostat was optimized for producing helium droplets. The pulsed droplet beam appeared with a bimodal size distribution. The leading part of the pulse consists of droplets suitable for doping with molecules. The average size of this part can be varied between 104 and 106 helium atoms, and the width of the distribution is smaller as compared to a continuous-flow droplet source. The system has been tested in a single pulse mode and at repetition rates of up to 500 Hz with almost constant intensity. The droplet density was found to be increased by more than an order of magnitude as compared to a continuous-flow droplet source.

INN 2021 N2 - Zusammenfassung Nachhaltigkeitsbericht der Gemeinde Rott a. Inn 2021 Rott a. Inn ist eine kleine Gemeinde im Süden des deutschen Bundeslandes Bayern. Mit ihren rund 4.000 Einwohnern repräsentiert sie größenmäßig eine durchschnittliche Kommune in ihrer Region. Sie liegt rund 50 Kilometer von der nächstgelegenen Metropole München entfernt. Mit der Erstellung eines Nachhaltigkeitsberichts nimmt Rott a. Inn in Deutschland eine Vorreiterrolle ein. Kaum eine Kommune ihrer Größe hat bisher einen solchen Bericht veröffentlicht. Um den Bericht in die globalen Nachhaltigkeitsbestrebungen einzubetten, wurde dieser streng an den 17 Sustainable Development Goals (SDGs) der Vereinten Nationen ausgerichtet. Der Nachhaltigkeitsbericht ist zweigeteilt: im ersten Teil berichten verschiedene Akteure und Institutionen der Kommune über Ihre Bestrebungen für eine nachhaltige Entwicklung. Die Gemeindeverwaltung unter Führung von Bürgermeister Daniel Wendrock legt darin bereits umgesetzte Maßnahmen, Projekte, die sich noch in der Umsetzung befinden und mittelfristige Pläne dar. Daneben berichten die Referenten des Gemeinderats, die Beauftragten der Gemeinde, Vertreter von Arbeitskreisen, Verbänden, der Schule, der Kirchengemeinschaft und der Wirtschaft über ihre Bemühungen. Eine qualitative Einschätzung ist auf Basis des ersten Teils des Nachhaltigkeitsberichts aufgrund seines individuellen Charakters nur schwer möglich. Es zeigt sich jedoch, dass die aktuellen Herausforderungen und die Notwendigkeit von nachhaltigem Handeln bei den verschiedenen Akteuren durchaus präsent sind. Entsprechende Bemühungen werden von den Entscheidungsträgern der Kommune aktiv unterstützt. Der zweite Teil des Nachhaltigkeitsberichts ist datengestützt. In ihm werden anhand von 78 Indikatoren relevante Bereiche untersucht. Jedem der siebzehn SDGs wurden mehrere solcher Indikatoren zugeordnet. Im Ergebnis wird deutlich, dass die Gemeinde zwar einige Zielwerte bereits erreicht, in anderen Bereichen jedoch noch Nachholbedarf hat. Dies betrifft beispielsweise den Ausbau der erneuerbaren Energien oder den Anteil von Frauen in Führungspositionen in Politik und Verwaltung. Besonders deutlich wurde darüber hinaus, dass es in vielen Bereichen an einer validen Datengrundlage mangelt. Hier müssen Verbesserungen in der Kommune selbst, aber auch durch die übergeordneten Ebenen erfolgen. N2 - Summary of the Sustainability Report Rott a. Inn 2021 Rott a. Inn is a small municipality in the south of the german state of Bavaria. Counting roughly 4,000 inhabitants, it represents an averagely sized municipality in its region. It is located about 50 kilometers from the nearest major city, Munich. With the preparation of a sustainability report, Rott a. Inn has taken on a pioneering role in Germany. So far, hardly any other municipality of its size has published such a report. To embed the report in global sustainability efforts, it was strictly aligned with the United Nations' 17 Sustainable Development Goals (SDGs). The sustainability report is divided into two parts: in the first part, various parties and institutions of the municipality report on their efforts for sustainable development. The municipal administration, led by Mayor Daniel Wendrock, presents measures that have already been implemented, projects that are still being implemented and medium-term plans. In addition, the speakers of the municipal council, the commissioners of the municipality, representatives of working groups, associations, the school, the church community and the business community report on their efforts. As the first part of the sustainability report is individual in nature, it is difficult to make a hereon based qualitative assessment. However, is clearly visible that the various parties are aware of the current challenges and the need for sustainable action. Corresponding efforts are actively supported by the decision-makers of the municipality. The second part of the sustainability report is data-based. It examines relevant fields based on 78 indicators. Several such indicators have been assigned to each of the 17 SDGs. The result demonstrated that although the municipality has already achieved some target values there is still room for improvement in others. This applies, for example, to the expansion of renewable energies or the proportion of women in leadership positions in politics and administration. It also became particularly clear that there is a lack of valid data in many areas. Improvements must be made here, both in the municipality itself and on higher levels. N2 - Resumen del Informe de Sostenibilidad de Rott a. Inn 2021 Rott a. Inn es un pequeño municipio en el sur del estado alemán de Baviera. Con sus aproximadamente 4.000 habitantes, representa un municipio medio en su región en términos de tamaño. Se encuentra a unos 50 kilómetros de Múnich, la metropolis más cercana. Con la elaboración de un informe de sostenibilidad, Rott a. Inn ha asumido un papel pionero en Alemania. Casi ningún municipio de su tamaño ha publicado hasta ahora un informe de este tipo. Con el fin de integrar el informe en los esfuerzos globales de sostenibilidad, se alineó estrictamente con los 17 Objetivos de Desarrollo Sostenible (ODS) de las Naciones Unidas. El informe de sostenibilidad se divide en dos partes: en la primera, los diferentes actores e instituciones del municipio informan sobre sus esfuerzos en pro del desarrollo sostenible. La administración municipal, dirigida por el alcalde Daniel Wendrock, presenta las medidas que ya se han aplicado, los proyectos que aún se están ejecutando y los planes a medio plazo. Además, los portavoces del consejo municipal, los representantes del municipio, los representantes de los grupos de trabajo, las asociaciones, la escuela, la comunidad eclesiástica y la comunidad empresarial dan cuenta de sus esfuerzos. Es difícil hacer una evaluación cualitativa sobre la base de la primera parte del informe de sostenibilidad debido a su carácter individual. Sin embargo, se puede observar que los desafíos actuales y la necesidad de una actuación sostenible están definitivamente presentes en la mente de los distintos actores. Los esfuerzos correspondientes cuentan con el apoyo activo de los responsables del municipio. La segunda parte del informe de sostenibilidad se basa en datos. Examina las áreas relevantes sobre la base de 78 indicadores. Se asignaron varios de estos indicadores a cada uno de los diecisiete ODS. Como resultado, queda claro que aunque el municipio ya ha alcanzado algunos objetivos, todavía tiene que ponerse al día en otras áreas. Esto se refiere, por ejemplo, a la expansión de las energías renovables o a la proporción de mujeres en puestos de liderazgo en la política y la administración. También queda especialmente claro que hay una falta de datos válidos en muchos ámbitos. Las mejoras deben realizarse en el propio municipio, pero también en los niveles superiores.

Ein Praxisleitfaden auf der Basis der Sustainable Development Goals (SDGs) N2 - Nachhaltigkeit messbar machen Nachhaltigkeitsberichte sind DAS Instrument, um den aktuellen Stand der drei Nachhaltigkeits-Dimensionen (ökonomisch, ökologisch und sozial) in einer Kommune glaubwürdig zu bilanzieren. Die eigenen Anstrengungen, aber auch Problemfelder und Herausforderungen werden herausgearbeitet. Die Erkenntnisse aus dem Bericht helfen dabei, Entscheidungen zugunsten von Artenvielfalt und Klimaschutz durchzusetzen und die Lebens- und Wohnqualität in der Kommune zu erhöhen. Viele Städte und Gemeinden scheuen jedoch den Aufwand. Die Intention dieses Buches ist es daher, die Verbreitung kommunaler Nachhaltigkeitsberichte zu fördern und zu erleichtern. Dafür wird ein eigenes Konzept auf Basis der Sustainable Development Goals (SDGs) vorgestellt, das auf Gemeinden jeder Größe anwendbar ist. Der Leitfaden Kommunale Nachhaltigkeitsberichte bietet Verantwortlichen und Interessierten Orientierung und unterstützt bei der praktischen Umsetzung: • Warum ist es notwendig und sinnvoll, über Nachhaltigkeit zu berichten? • Woher lassen sich Daten und Fakten der Kommune einholen? • Mit welchem Zeitaufwand ist zu rechnen? • Welche Handlungsfelder der kommunalen Aufgaben sind für die nachhaltige Entwicklung relevant? • Welche Indikatoren können zur Abbildung der SDGs auf lokaler Ebene herangezogen werden? Welche Stellen bieten Unterstützung an? Viele Praxis-Tipps und zahlreiche Beispiele vereinfachen darüber hinaus die Berichterstellung. Die Autoren haben ihr Konzept in der bayerischen Gemeinde Rott a. Inn erprobt – Nachmachen ist ausdrücklich erwünscht. N2 - Making sustainability measurable Sustainability reports are the best available instrument for measuring the sustainability of a municipality. It is measured across three dimensions (economic, ecological and social). The community's own efforts, but also problem areas and challenges, are highlighted. The findings from the report help to enforce decisions in favor of biodiversity and climate protection and to increase the quality of life and living in the municipality. However, many cities and communities shy away from the effort. The intention of this book is therefore to promote and facilitate the dissemination of municipal sustainability reports. To this end, it presents its own concept based on the Sustainable Development Goals (SDGs), which can be applied to municipalities of any size. The guide Municipal Sustainability Reports offers orientation to responsible and interested parties and supports practical implementation: • Why is it necessary and useful to report on sustainability? • Where can data and facts about the municipality be obtained? • How much time is needed? • Which fields of action of the municipal tasks are relevant for sustainable development? • Which indicators can be used to map the SDGs at the local level? Which agencies offer support? Many practical tips and numerous examples also simplify the report preparation. The authors have tested their concept in the Bavarian municipality of Rott a. Inn - imitation is highly encouraged. N2 - Hacer que la sostenibilidad sea medible Los informes de sostenibilidad son un instrumento para evaluar de forma creíble el estado actual de las tres dimensiones (económica, ecológica y social) de la sostenibilidad en un municipio. Se destacan los propios esfuerzos del municipio, tanto como las áreas problemáticas y los desafíos ante las cuales se vea. Las conclusiones del informe ayudan a tomar decisiones en favor de la biodiversidad y la protección del medioambiente y a aumentar la calidad de vida de los habitantes del municipio. Sin embargo, muchas ciudades y municipios rehúyen el esfuerzo. La intención de este libro es, por tanto, promover y facilitar la difusión de los informes de sostenibilidad municipales. Para ello, presenta un concepto propio basado en los Objetivos de Desarrollo Sostenible (ODS), que puede aplicarse a municipios de cualquier tamaño. La guía Informes municipales de sostenibilidad ofrece orientación a las personas responsables e interesadas y apoya la aplicación práctica: - ¿Por qué es necesario y útil informar sobre la sostenibilidad? - ¿Dónde se pueden obtener datos y hechos sobre el municipio? - ¿Cuánto tiempo hay que dedicar? - ¿Qué ámbitos de actuación de las tareas municipales son relevantes para el desarrollo sostenible? - ¿Qué indicadores pueden utilizarse para representar los ODS a nivel local? ¿Qué organizaciones ofrecen apoyo? El libro (la guía?) ofrece muchos consejos prácticos y numerosos ejemplos que simplifican la elaboración del informe. Los autores han puesto a prueba su concepto en el municipio bávaro de Rott a. Inn; se recomienda expresamente la imitación.
