A general approximation method for accurate evaluation of the intermolecular potential parameters by using density functional theory

open access: yesKuwait Journal of Science
In this work, a new approach is developed and presented for determining the intermolecular potential parameters from intermolecular interaction energy data obtained using the Density Functional Theory (DFT) method over a different basis set. The proposed

The effect of anisotropy on the second virial coefficient of H-2

open access: yes, 2000
We have calculated the second virial coefficient B(T),B(T), including quantum corrections, from a pair potential for hydrogen recently developed from ab initio calculations.

Accurate assessment of the Boyle temperature of nonpolar molecular gases using second virial coefficient with Lennard-Jones (12-6) potential

open access: yes, 2019
WOS: 000467484800002We derived an efficient analytical formula to calculate the second virial coefficient in the Lennard-Jones (12-6) potential. The analytical formula is used to accurately evaluate the Boyle temperature.

On the osmotic second virial coefficient of athermal polymer solutions

open access: yes, 1974
The osmotic second virial coefficient A2(n) of athermal polymer solutions is discussed for a simple lattice model, each molecule (n - mer) corresponding to a self-avoiding walk of n - 1 steps on a simple cubic lattice.
