The high pressure dependence of the linewidths of the D/sub 2/ polarized Q branch of the Stokes Raman ..nu.. = 0..-->..1 transition is calculated numerically and compared with the experimental linewidths. These linewidths are computed using the Shafer--Gordon formula for the line broadening cross section. The requisite S matrices are determined from an ab initio D/sub 2/--He interparticle potential averaged over D/sub 2/ vibrational wave functions. These wave functions were also calculated with an ab initio D--D potential. Thus, there were no adjustable parameters for the linewidth calculations. In the high pressure limit, the calculated linewidths matched the experimental linewidths to within about 5%
