An improved form of the nonanalytic equation of state is used to compute thermodynamic properties of carbon monoxide along isobars up to 100 MPa, at integral temperatures from coexistence to 1000 K.

A survey of the available experimental data and the existing equations for the refractive index of water is given. The dependence of the molar refraction on wavelength, temperature, and density is shown over an extended range. Based upon the electromagnetic theory of light an equation for the refractive index of water with wavelength, temperature, and density as independent variables is constructed. Its coefficients are directly deduced from all available experimental data by least‐squares fit. The range of validity of wavelength is restricted by the theory for normal dispersion to 182 nm≤λ≤2770 nm. The range of temperature and density is given by the available experimental data. Interpolations between the single measured points are possible and the following range of validity can be recommended: for temperature −10 °C≤T≤500 °C and for density 0.0028 kg/m3 ≤ρ≤1045 kg/m3. Good agreement exists between the new relation, the available experimental data, and several existing equations.

In view of the importance of air in science and technology and the abundance of experimental data, we present in this report a consistent set of critically evaluated data and an up‐to‐date correlation of the viscosity and the thermal conductivity of air in the gaseous phase over a wide range of temperature and pressure. This is especially important for the viscosity, since the recent data show systematic differences compared with the old standard value used for many years. The present paper was written in order to document the critical evaluation of the latest data sets and to present a new set of correlations of the viscosity and the thermal conductivity of air. The range covered is from 85 to 2000 K for temperature and up to 100 MPa for pressure.

Cross sections and equilibrium fractions for energetic H+, H−, and H0 in collisions with metal‐vapor targets have been compiled and evaluated. Both experimental and theoretical results are reported. Sources of errors are discussed, and recommended values for the data are presented.

Kinetic data for the superoxide radical (HO2⇄O− 2 +H+, pK=4.8) in aqueous solution have been critically assessed. Rate constants for reactions of O− 2 and HO2 with more than 300 organic and inorganic ions, molecules and other transient species have been tabulated.

In this review, the second in a series, the viscosity–molecular weight (Mark–Houwink–Sakurada) relationships have been critically evaluated for atactic polystyrene for a variety of solvents often used for viscosity measurements. These are benzene, toluene, 1,2,4‐trichlorobenzene, tetrahydrofuran, o‐dichlorobenzene, 2‐butanone, and two theta solvents, cyclohexane and decalin. In addition, the Mark–Houwink–Sakurada parameters for several other solvents, not used as frequently, are provided.
Standard Chemical Thermodynamic Properties of Alkylcyclopentane Isomer Groups, Alkylcyclohexane Isomer Groups, and Combined Isomer Groups14(1985); http://dx.doi.org/10.1063/1.555741View Description Hide Description
The standard chemical thermodynamicproperties of the alkylcyclopentane isomer groups have been calculated through C9H1 8 in the ideal gas phase from 298.15 to 1000 K, and the properties of the alkylcyclohexane isomer groups have been calculated through C1 0H2 0. The properties of individual species for which literature data are not available have been estimated using the Benson method. The increments per carbon atom in the isomer group properties have been calculated to determine the extent to which extrapolations may be made to higher carbon numbers. Since alkylcyclopentanes and alkylcyclohexanes of the same carbon number are isomers, the chemical thermodynamicproperties of these combined isomer groups have also been calculated. Values of C ○ P , S ○, Δf H ○, and Δf G ○ are given for the individual cyclopentane species through C9H1 8 and for the individual cyclohexane species through C1 0H2 0 for a standard state pressure of 1 bar.
