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-
