Impact theory for the noble gas pressure-induced HCl vibration-rotation and pure rotation line shifts—II

Abstract

The impact theory presented in a previous article is applied to the calculation of the noble gas pressure-induced shifts of the 0–1, 0–2 and pure rotational band lines of HCl. The results compare reasonably well with experiment, in that the theory explains in large part the dependence of the shifts on the rotational and vibrational quantum numbers as well as the polarizability of the noble gas perturber. Further modifications which could improve the agreement with experiment are discussed briefly.
