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
