## Abstract The appearance of [MHโ€30]^+^ ions in the chemical ionization mass spectra of aromatic nitro compounds may be due to their initial reduction to the corresponding amines within the ion source. Aromatic nitroso compounds may be similarly reduced to yield [MHโ€14]^+^ ions. The hydroxy deriva

The methane negative-ion chemical ionization (NCI) mass spectrum of chlorprothixene shows an unusual MHion. This ion can be accounted for by electron capture followed by H transfer from the reagent gas. The most probable site of electron attachment was concluded to be related to the sulfur atom of t
