1. The quantum-chemically calculated proton affinity may be considered a convenient index, characterizing the relative coordinating capacity of the different electron-donor sites of the amides and hydrazides of pyridinecarboxylic acids. 2. The calculated change in the electronic structure of the bonds in these molecules upon proton coordination qualitatively corresponds to the nature of the change in their IR spectra upon complexation.
