The vibrational densities of states in the lattice translation region below 130 cm-' (3 THz) for structure I xenon hydrate and structure II krypton hydrate have been determined from incoherent inelastic neutron scattering experiments. The main features in the lattice vibrations are found to shift to

## Abstract We present an extremely simple formulation of inelastic incoherent neutron scattering from impure crystals. The formulation treats both mass and centralβforceβconstant changes at the defect site in a closed form which is immediately amenable to an experimental analysis.
Inehstic neutron scattering spectra of KHCO3 and CsH(NO& have been obtained in the region 400 -. 2400 and 400 -+ 2800 cm-' respectively\_ The in-and out-ofqhase bending vibrations of the hydrogen bonds have been observed and assigned. For CsH(NO& the two bending modes are closer in frequency than in
