On the basis of our previous results (G. Kronome, J. Liszi and I. Szal
ai, J. Chem. Sec., Faraday Trans., 1997, 93, 3053) a new analytical eq
uation of state is predicted for Stockmayer gases. It is shown that, a
t different dipole moments, the isotherms of our new equation of state
are in better agreement with the Monte Carlo simulation results than
the appropriate perturbation theoretical and virial equation of state
based data.
