Abstract

Single-photon transition moments for overtone states of triply degenerate modes of spherical-top molecules applicable to multiple-photon dynamics calculations are derived for zeroth- and first-order theories. In each case the total transition strength for excitation out of a given angular momentum state is in agreement with well-known results for the triply degenerate oscillator. In contrast with recently published results, this work shows that all strongly allowed multiple-photon pathways do occur.
