The photodissociation of thiophosgene at 248 nm

Abstract
A pulsed molecular beam of thiophosgene was photodissociated at 248 nm. The detection of CSCl and Cl2 fragments formed under collision free conditions is evidence for two decomposition pathways: (a) CSCl2 → CSCl+Cl (b) CSCl2 → CS(X 1Σ)+Cl2. An estimate for the quantum yield for (a) is calculated to be 0.8±0.1. An impulsive spectator model is consistent with the measured translational energy distribution in process (a) for which on average 16±2 kcal/mol is found as translational energy. The results imply a vibrationally excited CSCl fragment.
