DISSOCIATION OF DOUBLY CHARGED SH RADICALS - AN EXPERIMENTAL AND THEORETICAL-STUDY

Ion translational energy spectrometry has been applied to study unimolecular and collision-induced dissociation of dications of the SH radical. Experimentally determined values of the kinetic energy released upon dissociation are satisfactorily correlated with results of high-level ab initio calculations of potential energy curves of the ground and low-lying excited electronic states of SH2+ ions. Quantum-chemical methods in which configuration interaction effects are accounted for via the coupled-cluster approach are employed.
