| van der Waals forces |
The physical forces of attraction and repulsion existing between molecules and which are responsible for the cohesion of molecular crystals and liquids. The forces stem partly from dipole-dipole, or dipole-induced-dipole interactions; however, even nonpolar molecules and atoms exert a certain attraction on one another. Van der Waals forces act only over relatively short distances, and are proportional to the inverse of the seventh power of the intermolecular distances.
