Abstract

The line shape parameters for the collision-induced vibration-rotation spectrum of HD-He are calculated with the formalism of Gao et al. The total intensity interference parameters and line asymmetry parameters are found to be larger than those for pure rotational transitions. The results depend on collisional propagation among rotational levels in both vibrational states and can be sensitive to vibrational-state dependence of the intermolecular potential.
