Dispersion or London forces are large networks of intermolecular forces between nonpolar and non-charged molecules and atoms (i.e. alkanes, noble gases, and halogens).

Molecules that have induced dipoles may also induce neighbouring molecules to have dipole moments, so a large network of induced dipole-induced dipole interactions may exist.

Van der Waals interactions involve instantaneous dipoles and induced dipoles that arise because of fluctuations in the electron charge distributions of adjacent nonbonded atoms.
