Abstract

We report observations of the Raman-active vibrational overtone in normal deuterium at 77K and pressures up to 36.4 GPa (1 GPa = 104 bar). We observed a sharp Q2(J) line corresponding to the v=2←0, ΔJ=0, k=0, Δk=0 transition and a broad Q1(J)+Q'1(J) band corresponding to v,v'=1←0, ΔJ=0, k≈-k' transitions. The selection rules for the Q1(J)+Q'1(J) manifold allowed us to measure the joint density of states of the manifold which we compared to a theoretical density of states for the v=1 vibrational band.
