Abstract

Einstein A coefficients have been calculated for rovibronic lines of the A²Π →X²Σ⁺ and B'²Σ⁺ →X²Σ⁺ transitions of 24MgH. Using the experimentally determined analytic potential energy curve for the X²Σ⁺ state, and the Rydberg-Klein-Rees potentials for the A²Π and B'²Σ⁺ states, combined with the most recent ab initio transition dipole moments, rovibronic transition moments were computed. The rovibronic transition frequencies were obtained accurately by subtracting the published term values of the X²Σ⁺, A²Π and B'²Σ⁺ states. Using the rovibronic transition dipole moments, transition frequencies and the Hönl-London factors, the Einstein A coefficients were calculated individually for ~30 000 rovibronic lines of the A²Π→X²Σ⁺ and B'²Σ⁺ →X²Σ⁺ transitions of ²⁴MgH. © 2013 The Authors
