A comparison of data on the viscomagnetic effect, flow birefringence and depolarized Rayleigh line broadening for various gases of linear molecules at temperatures between 90 and 293 K is carried out. From the combined results information is obtained on the scalar structure of the...

Experimental results are presented for the magnetic field effect on diffusion in N2-noble gas mixtures at 300 K. The data show that the polarization produced by a concentrating gradient is different from the one produced in a temperature gradient and that this different is due to a different...

Collisional broadening of rotational Raman lines has been investigated for the gases nH2, nD2 and HD between 20 and 300 K. For H2 and D2 the dependence of the linewidth on ortho-para composition has been investigated. For a number of systems the pressure shift of the Raman lines has also been...

Experiments have been performed to study the influence of a magnetic field on the Dufour effect (or diffusion-thermo effect) in an equimolar N2Ar mixture at room temperature. By comparing these experimental results with those obtained previously for the field effect on the thermal diffusion,...

Effects of magnetic and electric fields on transport phenomena in dilute polyatomic gases are reviewed within the framework of first order Enskog theory. The established technique of approximate operator inversion is used to give first order approximations of the transport coefficients. Instead...

Experiments on the influence of a magnetic field on the thermal diffusion (DT) have been performed. Both the transverse coefficient, DtrT, as well as the difference between the longitudinal coefficients, D⊥T − DT, were measured for binary mixtures of N2, nD2, HD and nH2 with the nob le...

In order to obtain information on the scalar structure of non-equilibrium polarizations a comparison between the magnetic and the electric field effect on the viscosity of some symmetric top molecules has been carried out. It is shown that the polarization produced in viscous flow is more...

A method is described for directly inverting measurements of the total scattering cross section at velocities beyond the glory undulations to determine the intermolecular potential, without the use of specific mathematical models for the potential. The only parameter needed is a quantity...

The kinetic theory of polyatomic and multipolar gases is used to obtain a general correlation that gives the thermal conductivity at low density in terms of known quantities: other gas properties (viscosity, specific heats, and mass diffusion coefficient); structural parameters (dipole and...

This paper contains the background for a complete synthesis of all the properties-equilibrium as well as transport—of the five noble gases and of the 26 mixtures that can be formed with them. The synthesis is valid for the zero-density limit only, but covers the temperature range from absolute...
