Photodissociation dynamics of H2S(D2S) following excitation within its first absorption continuum

Article abstract of DOI:10.1063/1.458093

The technique of H(D) atom photofragment translational spectroscopy has been applied to the photodissociation of H2S(D2S) following excitation at a number of wavelengths in its first absorption continuum.The respective bond dissociation energies were determined as D₀(H-SH) = 3.90 +/- 0.03 eV and D₀(D-SD) = 4.00 +/- 0.02 eV.The measured vibrational energy disposal in the partner ground state SH(SD) fragments and the product angular distributions support and extend the earlier results of van Veen et al. , while the deduced rotational andspin-orbit state population distributions in these fragments appear to be generally consistent with the recent measurements of Weiner et al. .We present a schematic adiabatic potential energy surface for the dissociative ¹A'' excited state via which it is possibe to rationalize virtually all existing dynamical measurements relating to this fragmentation process.
