Phys., submitted] has been extended to mixtures of HD, D-2 and T-2 with He-3 and He-4. For HD-He-4 mixtures, comparison is also made, where possible, with previous calculations of Kohler and Schaefer [1983, Physica A, 120, 185]. The phenomena examined herein include low temperature interaction second virial coefficients, binary diffusion and thermal conductivity coefficients, rotational relaxation, transport property field effects and flow birefringence. Scattering calculations have been carried out for the HD-He PES of Schaefer and Kohler [1985, Physica A, 129, 469], and for both the Kohler-Schaefer and Tao [1994, J. chem. Phys., 100, 4947] potential surfaces for the D-2-He and T-2-He interactions. Comparisons between calculated and experimental results for HD, D-2, T-2-He mixtures confirm the conclusion, reached earlier from the H-2-He comparisons, that these potential surfaces are very close to the correct one for the hydrogen-helium interaction, and that the small differences between them cannot be distinguished readily by measurements of bulk gas phenomena unless the attendant experimental uncertainties are better than +/-0.3\%.}, keywords = {AB-INITIO CALCULATION, BOILING-POINT, DEUTERON MAGNETIC-RESONANCE, GAS-MIXTURES, LINE-SHAPES, NOBLE-GASES, POTENTIAL-ENERGY SURFACE, RAMAN-Q-BRANCH, ROTATIONAL RELAXATION, THERMAL-DIFFUSION FACTOR}, isbn = {0026-8976}, url = {://000226263800006}, author = {McCourt, F.

The experimental AES of the polymers can be classified in each range of ls-2p2p, 1s-2s2p, and 1s-2s2s transitions for CKVV and OKVV spectra, and in individual contributions of the functional groups from the theoretical analysis.
