## Abstract The 70 eV electron impact mass spectra of some 1,3,4‐thiadiazolo[3,2‐__a__]pyrimidin‐7‐one and isomeric‐5‐one derivatives are discussed with the aid of defocused metastable spectra and exact mass measurements. The compounds are shown to be very stable to electron impact and ring contrac
