Abstract
The D2 vibrous have been studied by high-resolution Raman scattering in mixed crystals of (p-D2)x(o-D2)1-x. The o-D2 and p-D2 vibrational transitions are found to overlap. Line shapes calculated by the coherent potential approximation are in good qualitative agreement with the experimental data. The linewidth of the o-D2 transition is much larger than the linewidth of the p-H-2 transition in (o-H-2)x(p-H-2)1-x mixed crystals with comparable J = 1 concentrations. Possible explanations for this difference are discussed.
