Improvement of the RKR procedure obtained by semi-classical calculations

Abstract In this letter we present a new technique to improve RKR molecular potential curve calculations. The potential curve obtained gives calculated G (ν) and B (ν) values extremely close to the measured ones. The aim of these calculations is the same as that of the inverted perturbation approach of Vidal and Sheingraber, but the potential-well corrections are calculated by using Watson's semi-classical inversion procedure.
