Use of time-resolved Raman scattering to determine temperatures in shocked carbon tetrachloride

We report on the use of time-resolved Raman scattering data to determine temperatures in liquid carbon tetrachloride shocked by step-wise loading to a peak pressure of 12 GPa. Changes in our previously reported experimental configuration have resulted in a significant improvement in the signal-to-noise ratio in the data and permitted us to analyze the stokes and antistokes intensities for more than one vibrational mode (314 and 460 cm−1 modes). Hence, better precision can be obtained for shock temperatures on the nanosecond time scales. Temperatures are reported in the 500–1000 K range with an experimental precision of approximately 8%–10%. Our data show that the equation of state for carbon tetrachloride reported in the literature provides temperature values that are significantly lower than the measured values. Various aspects of using Raman scattering data for determination of shock temperatures are discussed.
