Diffusion coefficients for four equimolar binary gaseous mixtures of NO–noble gases are determined from the principle of corresponding states of viscosity by the inversion technique. The Lennard–Jones 12-6 (LJ 12-6) potential energy function is used as the initial model potential required by the technique. The interaction potential energies from the inversion procedure reproduce diffusion coefficients within 5%.

Viscosity and diffusion coefficients for four equimolar binary gaseous mixtures of CF 4 with O 2, N 2, CH 4 and CO 2 are determined from the extended principle of corresponding states by the inversion technique. The Lennard–Jones 12-6 (LJ 12-6) potential energy function is used as the initial model potential required by the technique. The interaction potential energies from the inversion procedure reproduce viscosity within 1% and diffusion coefficients within 5%.
