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

## Abstract The benzene‐induced solvent effects upon the proton chemical shifts of various pyrazines, pyrimidines and their __N__‐oxides are described. Larger chemical shift effects, implying closer benzeneheterocycle association, are noted in the __N__‐oxides as compared to the non‐oxidized hetero
