Theoretical Investigation of the Transition Probabilities in the Hydrogen Molecule

Abstract

The electronic transition moments for the B–X, C–X, and E, F–B transitions in the hydrogen molecule are given for several internuclear separations, R≤12 a.u. The electronic transition moments are used for the computation of the transition moments for individual vibrational and rotational lines. The results show that, except for the Werner bands, the relative intensities cannot be accurately represented by the Franck–Condon factors. It is not possible to make a definite quantitative comparison of the present results with experiment due to a significant R dependence of the electronic moments. Qualitatively, the results agree well with experiment. However, they do not explain the fact that the lowest vibrational levels in the F state have not yet been observed.
