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-

The mass spectral fragmentations of some 2,3-diaryl-l,3-thiazolidin4ones were established by comparing spectra and by using exact mass measurements. The major fragment ions were identified and their relative importances related to substituent effects and bond strengths. Good correlations were observ
