Abstract
The intensity of the pure rotational absorption spectrum of gaseous HD is measured as a function of density for pure HD and HD-He and HD-Ar mixtures at 295K. The decrease in the absorption coefficient with increasing density is consistent with a destructive intracollisional interference between transitions involving the permanent and collision-induced dipole moments. The permanent dipole moment of the molecule in its ground vibrational state is found to be J dependent and in the range $(8-10) \times 10^{-4}$ D.
