Comments on Second caloric virial coefficients for real gases and   combined spherical symmetric potential for simple molecular interactions
  It is shown that the interaction potentials for argon, krypton, xenon, carbon dioxide, ammonia, water, n-pentane, n-octane, 1-propanol, suggested in [1] cannot describe experimental second density virial coefficient data within their uncertainty over a wide temperature range.
