Abstract
The glassy behaviour of the thermal conductivities of structure I xeno n and structure II hydrate at high temperature are found to be describ ed surprisingly well by a localized oscillator model. This observation leads to the suggestion of strong coupling between the localized vibr ations of the guest with the lattice acoustic phonons. This conjecture is confirmed by a phenomenological calculation using the Anderson-Fan o resonant scattering model.
