Direct observation of pressure-induced amorphization of methane/ethane hydrates using Raman and infrared spectroscopy

Methane hydrate (MH) underwent pressure-induced amorphization (PIA) at 2–3.5 GPa, whereas ethane hydrate (EH) underwent PIA at 4.0–5.5 GPa. The structures of amorphous MH and EH are proposed based on the Raman and IR spectra.
