A method for group identification of poorly studied highly toxic O-alkyl alkylphosphonothionofluoridates by electron ionization mass spectra is proposed. The method is based on the use of generalized spectral images of four taxonomic groups of this class, subjected to control under the Convention on the Prohibition of Chemical Weapons. Generalized spectral images were found by analyzing the revealed regularities of fragmentation of these compounds. The advantage of the proposed method is that the assignment of the test substance to one of the class groups and to the class as a whole is a quick automated standard procedure used in the NIST information retrieval system.
