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