Resonances in the predissociation of the A [sup 2]pi[sub omega] state of MgBr.

Discusses the application of electronic structure methods and nonperturbative resonance theory to study the radiative and radiationless decay mechanisms of the magnesium bromide vibrational levels. Characterization of the adiabatic electronic states; Modification of the nonrelativistic potential energy curves in the first order degenerate perturbation theory.
