    <title language="eng">Symmetric geminal bisphosphinic acids RR´C[P(CH3)(O)OH]2 - NMR and analytical studies</title>
    <abstract language="eng">Four bisphosphinic acids RR´C[P(CH3)(O)OH]2 are characterized by 1H, 13Cf1Hg, and 31P{1H} NMR data. H3C-P-C-P-CH3 skeletons give rise to [A3X]2 spin systems. Some algebraic equations are derived for manual analysis of [A3X]2 spectra. HR NMR data for heteroaromatic substituents R in RC(H)[P(CH3)(O)OH]2 are reported. Dissociation constants and ion-specific chemical shifts dP of CH3C(OH)[P(CH3)(O)OH]2 are determined by 31P{1H} NMR controlled titrations of 2a.</abstract>
