Structural changes in pressure-amorphized THF-clathrates

Abstract: Clathrate hydrates are crystalline compounds in which water forms a host with cages that enclose guest molecules. Clathrate hydrates occur widely in nature with guest such as carbon dioxide and methane. At the same time, clathrate hydrates show interesting low-temperature behavior, which is similar to that of ice. Ice forms two different amorphous, or disordered, solid states when it is pressurized at low temperatures, below ca. -140 C. Since amorphous solid states may transform into liquids on heating, these two states provide evidence of the controversial suggestion that water can exist in two distinct liquid forms. Like ice, clathrate hydrates form an amorphous state when pressurized at low temperatures. Here we explore if pressure amorphized clathrate hydrates also exist in the form of a second amorphous state.
