Abstract

Temperatures from 3300–5200 K were measured in liquid H2O shocked to 50–80 GPa (500–800 kbar). A six-channel, time-resolved optical pyrometer was used to perform the measurements. Good agreement with the data is obtained by calculating the temperature with a volume-dependent Grüneisen parameter derived from double-shock data and a heat capacity at constant volume of 8.7 R per mol of H2O.
