THE RAMAN SPECTRA OF LIQUID AND SOLID H$sub 2$, D$sub 2$ AND HD AT HIGH RESOLUTION
The Raman spectra of liquid (18 deg K) and solid (2 deg K) n-H/sub 2/, p- H/sub 2/, n-D/sub 2/, o-D/sub 2/(80%), and HD were photographed with a reciprocal linear dispersion of 3 to 6 cm/sup -1/ but the Q/sub 1/ vibrational lines are very sharp. The S/sub 0/(0) transition of p-H/sub 2/ and o-D/sub 2/ is a triplet of sharp lines, but the corresponding transition in HD is not split. The vibrational frequencies in the liquid are lowered by 7 to 9 cm/sup -1/ and in the solid by 8 to 11 cm/sup -1/ from the gas values. The vibrational shifts in the various solids are correlated by representing them as the sums of shifts due to dispersion forces, overlap forces, and vibrational coupling. (auth)
