The Rayleigh scattering length has been calculated for rare-gas liquids in the ultraviolet for the frequencies at which they luminesce. The calculations are based on the measured dielectric constants in the UV in the gas phase, in some cases extrapolated to the wavelength of luminescence. The scattering length may place constraints on the design of some large-scale detectors, using UV luminesce...

In this paper, we review the state of the field of optical Kerr effect (OKE) spectroscopy of simple liquids, with a focus on results from our laboratory. We discuss the history and the theoretical underpinnings of this technique. We consider contemporary issues in the interpretation of OKE spectra, including the origin of the "intermediate" response and the factors affecting the shape of the re...

Vibrational energy relaxation of the NH-, OH-, and OD-stretching modes in hydrogen-bonded liquids has been investigated by means of infrared pump-probe spectroscopy. The relaxation rates have been determined both in neat liquids and in isotopic mixtures with systematically varied isotope fractions. In all liquids, the vibrational relaxation rate increases as the isotope fraction is increased an...

Infrared spectra of binary mixtures of water with hexane and decane were measured at temperatures and pressures in the 473-648 K and 70-350 bar ranges, respectively. Volumetric concentrations of water and the hydrocarbons in the mixtures were obtained from absorption intensities of the fundamental OH stretching band of HDO and combination transitions of the hydrocarbons. Using both the concentr...

Thermal conductivity of liquids and liquid mixtures has been a subject of active and considerable interest because of its technological applications as well as for providing an insight into the various molecular processes. Similarly, a study of thermal conductivity of liquids and liquid mixtures, at varying temperature and pressure, is of significance due to its applicability in process design,...

in this paper, the vapor-liquid equilibrium (vle) properties of polar and nonpolar fluids are modeled by the use of a statistically-based equation of state (eos). the equation of state used in this work is that of ihm-song-mason (ism) eos. an alternative approach is to revise the isothermal integration on liquid. in this respect, a temperature-dependent revision factor b (t) is introduced to th...
