Abstract

The D2 clathrate hydrate crystal structure was determined as a function of temperature and pressure. Neutron diffraction was used for the purpose of analysis. It was found that the hydrogen occupancy in the clathrate can be reversibly varied by changing the large cage occupancy between two and four molecules. Results show that above 130-160 K, the guest D2 molecules are in the delocalized state.
