A force acting between nonbonded atoms or molecules. Includes dipole-dipole, dipole-induced dipole, and London forces.

Weak attractive force between nonpolar molecules.

Any of several intermolecular attractive forces not resulting from ionic charges

A general term for all attractive forces that occur between electrically neutral molecules. Van der Waals forces include dipole-to-dipole interactions, hydrogen bonds, and other intermolecular forces.
