intermolecular force

[‚in·tər·mə′lek·yə·lər ′fōrs]
(physical chemistry)
The force between two molecules; it is that negative gradient of the potential energy between the interacting molecules, if energy is a function of the distance between the centers of the molecules.

Theoretically, Kalia and Vashishta (1981) and Zangi and Rice (1998) studied the melting transition of a colloidal monolayer using dipole-dipole interactions and a Marcus-Rice potential, respectively, with molecular dynamics (MD) simulations.
He suggested that the dipole-dipole interactions were responsible for the formation of 2-D ordered structures.
Hurd's results established Pieranski's suggestions (Pieranski, 1980) concerning dipole-dipole interactions at large separations between interfacial colloidal particles on a firm theoretical basis, and clarified the effect of the electrostatic interactions.
We used Hurd's asymptotic pair potential, which combines the screened Coulombic and dipole-dipole interactions.
