✦ Synopsis

The monosalt of 1,2,3-benzenetricarboxylic acid and that of 2,6-pyridinedicarboxylic acid N-oxide were studied in acetonitrile-d, solutions using NMR and IR spectroscopy.

In both molecules two intramolecular hydrogen bonds are formed. In the first molecule both protons fluctuate in a triple-minimum proton potential causing a large proton polarizability, whereas in the latter both protons are almost localized.
