英文摘要The kinetic energy releases of the photodissociation processes C6H5SH + h-nu (193 nm) --> C6H5 + SH, and C6H5SCH3 + h-nu (193 nm) --> C6H5 + SCH3 and C6H5S + CH3, have been measured by the time-of-flight mass spectrometric method. The available energies for these processes are found to appear predominantly (almost-equal-to 70-80%) as internal excitations for the photofragments. Based on the thresholds of kinetic energy release spectra, we obtain values of 87.4 +/- 2.0, 87 +/- 3, and < 81 +/- 7 kcal/mol for the dissociation energies of the C6H5-SH, C6H5S-CH3, and C6H5S-CH3 bonds at 0 K.
