## Abstract The mass spectra of a number O‐alkylthionocarbamates with two, one or no alkyl substituents on the nitrogen atom are presented and discussed. The main primary fragmentation pathways are McLafferty rearrangements, including the double so‐called protonated McLafferty rearrangement. Genera
The principal electron-impact fragmentation patterns of 3,4,5-triphenyl-l,2,4-triazole, 2,5-diphenyl-l,3,4-thiadiazole, their perfluorinated analogues and 2,5-di(pentafluorophenyl)-1,3,4oxadiazole have been established from metastable ion evidence and precise mass measurements. Although ions produce
