Quantum mechanical calculation of line shape parameters for the depolarized Raman Q branch of D2 in He

Results of quantum mechanical calculations of the spectral line widths, shifts, and line mixing parameters for the depolarized Ramanspectrum of D2 infinitely diluted in He are presented. An accurate ab initio H2He potential was used for the converged close-coupling calculations. The predicted trends for the D2He mixture agree reasonably well with measurements in pure D2.
