Determination of potential energy functions of CO-CO, CO2-CO2, and N2O-N2O and calculation of their

Abstract

The potential energy functions of CO–CO, CO2–CO2, and N2O–N2O systems have been determined via the inversion of reduced viscosity<br><br>collision integrals at zero pressure and fitted to obtain analytical potential forms. The potentials produce viscosity, thermal conductivity,<br><br>self-diffusion coefficient, and second virial coefficients of carbon monoxide, carbon dioxide, and nitrous oxide over wide temperature<br><br>ranges within experimental errors. The potentials of carbon monoxide and carbon dioxide have been compared with the recently obtained<br><br>ab initio potentials and the potential of nitrous oxide has been compared with the Stockmayer potential. We have also derived very accurate<br><br>equations for viscosity, self-diffusion coefficient, and second virial coefficient of CO, CO2, and N2O in a wide temperature range.
