van der Waals force

[′van dər ‚wȯlz ‚fȯrs]
(physical chemistry)
An attractive force between two atoms or nonpolar molecules, which arises because a fluctuating dipole moment in one molecule induces a dipole moment in the other, and the two dipole moments then interact. Also known as dispersion force; London dispersion force; van der Waals attraction.
