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

Mass spectra of seven related N-heterocyclics, introduced by direct exposure probe, were determined in electron impact (EI) and positive-and negative-ion chemical ionization (PCI and NCI) modes. Proton adducts were the predominant molecular ion species in the EI and PCI modes. In addition, a variety
## Abstract It has been shown by exact mass measurements and collision‐induced dissociation mass‐analysed ion kinetic energy spectra that the structure of the __m__/__z__ 124 ion observed in the mass spectra of __N__‐(4‐methoxyphenyl)thiophene‐2‐carboxamide, __N__‐(4‐methoxyphenyl)thiophene‐3‐carbo
