Abstract

A simple relation between the frequency of E2g phonon modes and the elastic constant C44, derived previously for hexagonal-close-packed metals, is found to be reasonably valid for crystals of solid He, H2, D2 and N2 at or near normal pressure. Good agreement at high pressure for n-H2 suggests that the connection between C44 and the phonon frequency also holds over a wide compressional range.
