The soft-sphere model is convenient and accurate for predicting fluid phase thermodynamics. The validity of the model for describing the equation-of-state derivatives, Gruneisen's gamma and sound velocity, is shown.

New experimental and computational methods make possible measurement or simulation of the thermodynamic properties of fluids over wide ranges of temperature and density. We use a model for fluid thermodynamics based on the (1/r)n repulsive potential

The wavelength shift with pressure of the ruby R1 fluorescence line (Δλ) has been calibrated in the diamond‐window pressure cell from 0.06 to 1 Mbar. This was done by simultaneously making specific volume measurements of four metals (Cu, Mo, Ag,

We present acoustic velocity data that demonstrate a high-pressure solid-solid phase transition in molybdenum at about 2.1 Mbar and 4100 K. This observation is supported here by first-principles theoretical calculations which predict a zero-temperatu

Recently sound speed measurements in high temperature liquid lead have been made over a wide density range. Such measurements may be combined with other thermophysical properties measured with the isobaric expansion experiment (IEX) to yield several

Backward stimulated Raman scattering measurements have been used to measure the frequency shift of the 992-${\mathrm{cm}}^{\ensuremath{-}1}$ vibrational ring-stretching mode of benzene shock-compressed to pressures of 0.6 to 1.2 GPa. Results of the d

An apparatus is described for making thermophysical measurements on liquid metals up to 0.4 GPa and 8000 K. Metal samples are resistively heated on a submillisecond time scale along an isobar. Techniques for measuring enthalpy, specific volume, elect
