TRADITIONAL TRANSPORT-PROPERTIES OF CO

Classical trajectory rigid-rotor calculations using higher-order kinetic theory expressions for shear viscosity, diffusion, volume viscosity and thermal conductivity have been performed using the anisotropic ab initio potential energy hypersurface of van der Pol et al. for the temperature range between 77 K and 1500 K. Comparison with experiment shows differences less than 1.2% with the best shear viscosity measurements, consistency with the relative diffusion coefficient data, an underestimate by up to 30% of the volume viscosity values and agreement with the thermal conductivity data between 120 K and 200 K but differences increasing to 7% at 430 K.
