The direct determination of intermolecular potential energy functions from gas viscosity measurements

Abstract

Abstract A new iterative method is proposed for the direct determination of potential energy functions from gas transport properties. Tests of the method on simulated data derived from a known potential function showed that it was capable of reproducing the original function with high accuracy. The method is used to obtain a potential energy function for argon from values of the gas viscosity coefficients in the temperature range 80–2000 K.
