Mass-spectra and molecular structure of O-alkyl N,N-dialkylamidocyanophosphates

The electron impact mass spectra were recorded and the key directions of fragmentation of the highly toxic O-alkyl N,N-dialkylamidocyanophosphates were identified. The sets of characteristic ions for the 10 subgroups of the main group of this class were determined. Based on the values of the mass numbers and peak intensities of characteristic ions generalized spectral images for each of the 10 studied subgroups of this class were simulated. A new method of group identification of O-alkyl N,N-dialkylamidocyanophosphates was developed.
