  Abstract:  The paper presents the fragmentation pattern proposed for the p-carboxybenzenesulfonamide (1), p-carboxy-methyl-benzenesulfonamide (2), p-methoxybenzenesulfonamide (3), and p-fluorinebenzenesulfonamide (4) of the O,O - diphenylthiophosphoric acid. The molecules behaviour under 70 eV electron impact was investigated based on their normal mass spectra, the accurate mass measurements and the metastable ions fragmentations. The kinetic energy release T50 was determined in the MIKE mode for the cleavages recorded in the second field free region, for compound 1, and the qualitative correlation is discussed, concerning the peak shapes, the amount of energy released, and the mechanism of decomposition proposed.
