title: Fascination with the conformational analysis of succinic acid, as evaluated by NMR spectroscopy, and why.
abstract: A serendipitous effort to use NMR spectroscopy to determine the conformational preferences of succinate monoanion opened a Pandora's box of unexpected uncertainties as to what influences such preferences of succinic acid in its various ionization states, not only in water but also in other less polar protic solvents, as well as a range of aprotic solvents. The dianion in aprotic solvents shows substantial gauche preferences, which give the appearance of violating Coulomb's law.
