The fragmentation behaviour of 3,4-disubstituted 1,2,4-oxadiazole-5(4H)-thiones under electron impact (EI) can be explained by postulating a predominant rearrangement to the corresponding 3,4-disubstituted 1,2,4-thiadiazole-5(4H)-ones before further fragmentation. This postulate is confirmed by a co
High resolution mass measurement established that the m/e 425 peak in the mass spectrum of 1,3-bis-(3-m-tolyI-l,2,4-oxadiazol-5-yl)hexafluoropropane corresponds to [M -CHNO]. This peak is absent from the mass spectrum of thepara isomer. ALTHOUGH the principal electron-impact fragmentations of the m
## Abstract The electron impact‐induced fragmentations of 2,3‐dihydro‐1,5‐benzothiazepin‐4(5__H__)‐ones and some related compounds were investigated. On the basis of low‐ and high‐resolution measurements, metastable ion studies by means of mass‐analysed ion kinetic energy spectroscopy and collision
