Abstract General scheme of fragmentation of monofunctional organic compounds RX (R, alkyl and X, functional group) has been elucidated basing on analysis of mass spectra under conditions of electron impact. The mass spectra have been considered as superposition of a few peaks of characteristic ions containing group X or its fragments and the peaks of hydrocarbon ions (hydrocarbon subspectra). The hydrocarbon subspectrum analysis has allowed interpretation of the fragmentation processes forming the RX compounds mass spectra and estimation of contribution of each process into the total ion current. The possibility of simulating the spectra of non-studied compounds RX via the transformation of available mass spectra of RX compounds with the same alkyl fragment is discussed. © Pleiades Publishing, Ltd., 2015.

A method is proposed for the prediction of electron-ionization mass spectra of highly toxic O-alkyl-N,N-dialkylphosphoramido cyanidates. The approach is based on the fact that the compounds can be divided into three groups by the type of fragmentation. The main group (O-alkyl, O-methyl, O-ethyl) containing almost all compounds of this class (61440 of 61460), in its turn, can be divided into ten subgroups characterized by different combinations of two N-alkyl radicals. Each subgroup possesses its specific generalized spectral image, i.e.; a set of peaks characterized by mass numbers and relative intensities. A spectrum of an individual O-alkyl-N,N-dialkylphosphoramido cyanidate is considered as a sum of the generalized spectral image of a corresponding subgroup and a spectrum of an alkene with a carbon chain identical to the O-alkyl group of the molecule. © 2011 Pleiades Publishing, Ltd.
