Notes: 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 - 1] anions. Most of the N-oxides yield O- and OH- ions. Polar substituents control the fragmentation processes involving the heterocyclic ring to which they are bonded.
