Mass spectra of picolinic, nicotinic and isonicotinic acids and of their respective N-oxides are presented. Picolinic acid and its N-oxide demonstrate the facile loss of carbon dioxide and low-intensity molecular ions. Fragmentation is relatively simple. Nicotinic and isonicotinic acids show very si
