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-

## Abstract 5‐Substituted 1,3,4‐thiadiazol‐2(3__H__)‐ones were shown to exist almost exclusively in the oxo tautomeric form with the aid of proton‐coupled ^15^N‐NMR spectra using the corresponding 3‐methyl‐1,3,4‐thiadiazol‐2(3__H__)‐ones and 5‐substituted‐2‐methoxy‐1,3,4‐thiadiazoles as reference c
