Yc. Kong et al., THE 2ND VIRIAL-COEFFICIENTS FOR WATER FROM MONTE-CARLO INTEGRATION USING REDUCED EFFECTIVE CHARGES, Molecular simulation, 13(1), 1994, pp. 39-46
The reduction of the dipole moment of effective pair potentials of rig
id water models enables accurate second virial coefficients to be dete
rmined over the whole temperature range. Subsequent Isothermal-Isobari
c (NPT) ensemble simulations of water vapour have shown that there is
a significant difference in vapour densities between the modified wate
r potentials.
