The k = 0 libron energies in solid hydrogen are calculated including the interactions between widely separated molecules. Comparing these results with the observed Raman spectrum gives the interaction coefficients, Г eff = 0.48 cm -1 for H 2 and Г eff = 0.67 cm -1 for D 2. These values are respectively 20 and 15 per cent lower than those obtained neglecting these interactions.
