Description

We report the results of Raman spectroscopy and quantum thermal bath molecular dynamics simulations in methane and hydrate at pressures up to 150 Gpa. We have found signatures of methane ordering, hydrogen bond symmetrisation and new high pressure phases.

Significance statement

We have shown the stability of methane clathrate up to 150 GPa. Shown the presence of new ordered phase.
