Abstract

Photodissociation dynamics of OCS and CS₂ adsorbed on water ice films at 90K was investigated at 193nm. by measuring the time-of-flight spectra of photodissociated S(¹D) and S(³P) atoms. The translational energy distributions are well represented by a combination of Gaussian and Maxwell-Boltzmann (M-B) distributions corresponding to the fast and slow time-of-flight components, respectively. Formation of the sulfur dimer on the ice surface is proposed as a secondary photoproduct. The fine-structure branching ratios of S(³P_J) from OCS and CS₂ adsorbed on H₂O or D₂O water ice films were also determined.
