Temperature determination in shocked condensed materials using Raman scattering

The use of time-resolved Raman scattering measurements to determine temperature in shocked materials is demonstrated. Experimental data were obtained by monitoring the stokes and antistokes intensities of the 460 cm−1 vibrational mode, at 50 ns intervals, in liquid carbon tetrachloride shocked to 12 GPa using step wise loading. The ratio of antistokes to stokes intensities changes in a pronounced manner with increasing pressure. Procedures to obtain precise temperatures are outlined, and improvements for future work are indicated.
