Isochoric P-T traces have been measured for solid argon at eight different molar volumes by using a capacitance technique which records the radial expansion of the vessel due to pressure. These measurements extend from melting curve temperatures down

Recent high-pressure equation-of-state data for Ar are analysed to obtain entropy, internal energy, and specific heat values for solid Ar from 84K to the melting curve at molar volumes from 21 to 24 cm3 mol-1. These equation-of-state data are also us

High temperature isochoric pressure-temperature traces in solid methane and nitrogen are used to evaluate ( ∂ P ∂ T ) v . A corresponding states analysis is presented; deviations from corresponding states are discussed in terms of molecular rotat

We have studied the collision-induced light-scattering spectrum of fluid methane at several densities between 75 and 780 amagats. The results indicate that only two- and three-body contributions are significant up to densities much higher than found

A hydrostatic pressure cell that can be used for the study of laser excited Raman spectra of solids as functions of pressure (up to 10 kbar) is described. Results on pressure induced phase transition and long-wavelength phonon frequency shifts of TlI

The transformation of rubidium iodide from its low pressure sodium chloride structure to its high pressure cesium chloride structure takes place at a pressure of about 3500 b. This transformation has been studied optically in single crystals, using a

Pressure dependences of the ferroelectric Curie temperatures of KH2PO4 and KD2PO4 were measured up to 2 kbar by neutron diffraction. A large isotope effect was observed in the Tc pressure coefficients: -4.52 ± 0.06°/kbar for KH2PO4 and -2.63 ± 0.0
