✦ Synopsis

A mass spectrometric identification and differentiation of pyrimidin-4(3H)-and -4(lH)-ones was carried out. NSubstitution at position 1 or 3 made the distinction of tbe two sets of compounds very easy because of their characteristic fragmentation pathways. Most interesting were the spectra of the N-unsubstituted derivatives, which illustrated a predominance of the two possible M I tautomers in relation to the Qhydroxy structure.

## 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
