  Abstract:  This work deals with the analysis of the fragment ions resulted under electron impact from the molecules of the: (1) p-methoxybenzenesulfonimide-, (2) benzenesulfonimide-, (3) p-chlorinebenzenesulfonimide-, and (4) P - methylbenzenesulfonimide - of the S - methyl, N, N - dimethyl-amidocyclohexylthiophosphonic acid. Mass spectra at 70 eV, metastable ions detection and accurate mass measurements were used to investigate the fragmentation processes.
