Abstract
A complete quantal phase‐shift calculation of the transport properties of gaseous H2, D2, HD, and some of their mixtures is presented from 10° to 300°K, based on the Lennard‐Jones (12–6) potential. It is found that H2 and D2 have slightly different intermolecular potentials, in agreement with evidence from other sources. Agreement between calculation and experiment is generally good, but there are some small but clear indications that the (12–6) potential model is oversimplified, such as the necessity to use slightly different potantial parameters for the transport properties than for the second virial coefficients.Keywords
