#### Abstract

*Einstein A* coefficients have been calculated for rovibronic lines of the A^{2}Π →X^{2}Σ^{+} and B'^{2}Σ^{+} →X^{2}Σ^{+} transitions of 24MgH. Using the experimentally determined analytic potential energy curve for the X^{2}Σ^{+} state, and the Rydberg-Klein-Rees potentials for the A^{2}Π and B'^{2}Σ^{+ }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 X^{2}Σ^{+}, A^{2}Π and B'^{2}Σ^{+} 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 A^{2}Π→X^{2}Σ^{+} and B'^{2}Σ^{+} →X^{2}Σ^{+} transitions of ^{24}MgH. © 2013 The Authors
