Dipole moment function of HI

Abstract

Quantum mechanical transition probabilities are presented for the 0-3 vibration-rotation band correct through two orders in γ = 2B e ω e . To lowest order, these agree with previous perturbation theory calculations but disagree with the analogous semiclassical results. Application is made to an analysis of the experimental intensity data of HI, and the dipole moment function M(ξ) = [1.445 ± .02 − (.0765 ± .0029)ξ + (.496 ± .040)ξ 2 − (1.94 ± .20)ξ 3] D, where x = (r − r e) r e is deduced.
