Multi-reference calculations of the photodissociation of HSCH₃ molecule

This paper performs multi-reference second-order perturbation theory calculations on the ground state and a number of low-lying excited states of HSCH_3 molecule, and calculates the vertical excitation energies and low-energy potential-energy curves, based on which the photodissociation channels of HSCH_3 at 193,222,248 nm are clarified.
