All coupling processes are mediated by vibrational overlap integrals, which are computed numerically. Semiclassical calculation of overlaps reveals physical factors controlling computed values: the length of the stationary phase region is controlled by the slopes of the potential curves at the intersection and the velocity in the crossing region.
