## Abstract The ^1^H NMR spectra of perchlorates of __N__‐(pyridyl)amides of 6‐methylpicolinic acid __N__‐oxide (PYAP) in CD~3~CN at 100 MHz show two proton signals belonging to two distinct intramolecular hydrogen bonds. The position of these signals is independent of concentration and temperature
