Spontaneous Raman spectroscopy of shocked H2O
Abstract
A new Raman spectroscopic system for recording spontaneous Raman spectra from shocked mater at high pressure and temperature during shock passage has been developed. This system is applied to the study of the OH-stretch band of water shocked to pressures between 7.5 and 25.7 GPa. The spectra indicate that strong intermolecular hydrogen-bonding persists to 12 GPa and decreases in strength at higher pressures. A two-component mixture model fits the data well under shock conditions.
