The vibrational density of states of amorphous beryllium hydride (a-Be H2) and lithium beryllium hydrides have been studied using inelastic neutron scattering, infrared, and Raman spectroscopies. The positions of the symmetrical (120-180 meV) and antisymmetrical (200-260 meV) Be-H stretching modes and those of the H-Be-H bending mode (50-120 meV) have been determined and the results discussed and compared with recent theoretical calculations. With the addition of lithium to the beryllium hydride network, the vibrational bands are shifted to lower energies, indicating a less rigid network.
