Abstract Electron ionization-induced loss of SO 2 from 2-nitrodiphenyl sulfide leads to the same ionic structure, or mixture of structures, as loss of N 2 from the molecular ion of N 1- phenylbenzotriazole. Ab initio calculations are in favor of the [C 6 H 4—N—C 6 H 5]+• distonic nitrenium radical cation instead of the N-phenylbenzo-Δ 2-azirinium structure for the product ion. Collisionally activated dissociation mass-analyzed ion kinetic energy (CAD- ...
