Theoretical dipole transition moments for the transitions to the ground state X²σ⁺from the A²σ⁺, B²Π, C²σ⁺, D²σ⁺and E²Π states and for the B²?A²:⁺system in HeH

Abstract

Dipole transition moments have been calculated for the transitions A2+ to X2+, B2 to X2+, C2+ to X2+, D2+ to X2+, E2 to X2+ and B2 to A2+ in HeH. The spectroscopic constants obtained in this work support an experimental assignment for the C 2+ to A 2+ transition.
