The negative-ion mass spectra of some pyridines, pyrazines and their N-oxides are reported. All of the compounds examined fragment by generation of CN-ions. The alkylated derivatives readily form [M -11 anions. Most of the N-oxides yield 0and OH-ions. Polar substituents control the fragmentation pro
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
## Abstract __N__(Pyrimidinβ2βyl)βglycine, βalanine and βphenylalanine (1β3) and their methyl esters (4β6) were investigated using electron impact (EI) mass Spectrometry. The results showed that EIβinduced decomposition occurs on the carboxylic group or involves the loss of R~2~OH. In contrast to e
