Our understanding of the deep carbon cycle has witnessed amazing advances in the last decade, including the discovery of tetrahedrally coordinated high pressure (P) carbonate phases. However, little is known about the physical properties of their mol

Raman spectroscopy demonstrates that the rotational spectrum of solid hydrogen, and its isotope deuterium, undergo profound transformations upon compression while still remaining in phase I. We show that these changes are associated with a loss of qu

We present a method for calculation of Raman modes of the quantum solid phase I hydrogen and deuterium. We use the mean-field assumption that the quantized excitations are localized on one molecule. This is done by explicit solution of the time-depen

The Raman spectra of liquid H 2 (D 2) have been collected in diamond anvil cell as a function of temperature at 3 GPa covering the range from 80 to ∼ 1000 K. Temperatures were measured using two independent methods: by thermocouple and from the rel
