Ab initio study of the low-lying states of SnH

Abstract

A comprehensive theoretical study is reported of the low-lying electronic states of SnH correlating with the three lowest Sn(³P, ¹D, ¹S) + H(²S) dissociation limits. The relativistic CI method based on effective core potentials has been employed to calculate potential energy curves and spectroscopic constants of these states, and good agreement with available experimental data is found. A number of as yet unobserved states is predicted to have minima on their potential curves. The radiative lifetimes for low-energy electronic transitions have also been computed.
