“…Since the early 1960s, eight independent measurements of viscomagnetic coefficients in nitrogen, carried out in three different laboratories, have been performed using capillary viscometers operating in a null mode. As a continuation of the measurements of Beenakker et al, 2 Korving et al 34 reported a first set of accurate measurements for nitrogen that clearly exhibited a viscomagnetic effect. They carried out measurements of the average of two longitudinal coefficients, −(∆η…”

“…1-4, the calculated values of the viscomagnetic coefficients are compared with the available experimental data (read from the published figures). No uncertainty estimate was given by the authors for the experimental data, although it was stated 34 that relative viscosity changes of 2 × 10 −6 could be detected. We start by comparing the calculated values to the measured ones for the longitudinal viscomagnetic coefficients.…”

Rovibrational structure of the Ar-CO complex based on a novel three-dimensional ab initio potential J. Chem. Phys. 117, 6562 (2002); 10.1063/1.1493180 This article is copyrighted as indicated in the article. Reuse of AIP content is subject to the terms at: http://scitation. The viscomagnetic effect for two linear molecules, N 2 and CO 2 , has been calculated in the dilute-gas limit directly from the most accurate ab initio intermolecular potential energy surfaces presently available. The calculations were performed by means of the classical trajectory method in the temperature range from 70 K to 3000 K for N 2 and 100 K to 2000 K for CO 2 , and agreement with the available experimental data is exceptionally good. Above room temperature, where no experimental data are available, the calculations provide the first quantitative information on the magnitude and the behavior of the viscomagnetic effect for these gases. In the presence of a magnetic field, the viscosities of nitrogen and carbon dioxide decrease by at most 0.3% and 0.7%, respectively. The results demonstrate that the viscomagnetic effect is dominated by the contribution of the jj polarization at all temperatures, which shows that the alignment of the rotational axes of the molecules in the presence of a magnetic field is primarily responsible for the viscomagnetic effect.

Waldmann on the occasion of his 60th birthdayThe magnetic Senftleben-Beenakker effect of the heat conductivity is considered for a gas of p-H2 molecules. The magnitude of the saturation value is expressed in terms of collision integrals of the linearized Waldmann-Snider collision term. The collision integrals are, in turn, connected with molecular cross sections describing the production of a tensor polarization of the molecular rotational angular momenta. These orientation cross sections depend essentially on the nonspherical part of the intermolecular potential. For small nonsphericity of the interaction, valid in the case of H2, it is sufficient to take into account only energetically elastic collisions For a simple poten tial model (nearly spherical rigid ellipsoids of revolution) the scattering amplitude is analytically evaluated in first order DWBA. The relevant collision integral which describes the coupling be tween the rotational heat flux and the Kagan polarization is calculated for room temperature. The comparison with the experimental value shows a good agreement.
