Title Methane molecular motion in clathrate hydrate host framework
Abstract Methane hydrate (MH)is a nonstoichiometric inclusion compound of methane with the host framework being composed of two kinds of water cages in a unit cell. We performed neutron inelastic measurements of MH to construct a scattering model of MH. The measurements were carried around 12 K with MARI spectrometer at ISIS in UK and TAS-2 spectrometer at JAERI in Japan. The experimental results show that methane molecular motion can be considered as a free rotor approximately and there still remains some excess peaks less than 10 meV. The origin of these peaks is considered as the localized translational motion of the methane molecule in two kinds of the water cages. (c) 2006 Elsevier B.V. All rights reserved.
