摘要

Gas hydrates are inclusion compounds formed from water and gas molecules. Guest molecules are distributed into cages of water framework. Although empty hydrate lattice is unstable under ambient conditions, the water-water interaction gives the main contribution to the total binding energy of gas hydrates. An important feature of ice and clathrate hydrates is a disorder in the proton positions. However, there are energy differences between various proton arrangements. The problem of proton ordering in ice has been the subject of much theoretical investigation. From the structural point, gas hydrate framework is composed entirely of eclipsed arrangement of hydrogen bonding. In this regard, gas hydrate frameworks are more structurally homogeneous than hexagonal ice.
