Abstract

The applicability of RKR—the true potential in comparison to that of Morse potential, has been tested for the transition (B 1Σ−X 1Σ) of BeO band system through various tests. The expressionR e(r), the electronic transition moment variation with internuclear distancer, using the Franck—Condon (FC) factors andr-centroids\(\left( {\bar r_{\nu '\nu ''} } \right)\) of the true potential has been derived and evaluated for both linear and quadratic fitting. This has further been used to calculate the smoothed Condon factorP n′n″ and the ratio β(=I/v4/P v′v″) representing its comparison with experimental band strengths (I/v 4). Through the comparative study of such values, viz.p v′v″ ’s ’s β’s and vibrational temperatures deduced both under constancy ofR e and the variation ofR e withr, the efficacy of true potential in relation to that of Morse potential has been discussed.
