Transport Collision Integrals for Gases Obeying 9–6 and 28–7 Potentials

Abstract

Collision integrals for the 9–6 and 28–7 potentials are tabulated over a range of reduced temperatures kT/ε from 0.01 to 100. The results are compared with previous results for the 12–6 and ∞−6 potentials, including a simultaneous analysis of second virial coefficients for all four potentials. The viscosities are rather similar over wide temperature ranges, but the isotopic thermal‐diffusion factors differ markedly.
