Abstract

The potential parameters of the exp : exp potential energy function have been determined utilizing the temperature dependence of thermal diffusion data for Neon, Oxygen and Nitrogen, The correctness of these values of potential parameters have been justified by computing the other transport properties of these gases. The coefficient of viscosity η and the coefficient of self-diffusion D have been computed in the case of Neon. For oxygen and Nitrogen the values of coefficient of self diffusion at different temperatures have been computed. The theoretical values of coefficient of viscosity and coefficient of self diffusion compare well with the experimental values. Furthermore the present parameters are more accurate than parameters evaluated, using the viscosity, virial and crystal properties. 1,2)
