, van der Waals interactions or Force
In physical chemistry, the van der Waals force (or van
der Waals' interaction), named after Dutch scientist
Johannes Diderik van der Waals, is the sum of the
attractive or repulsive forces between molecules (or
between parts of the same molecule) other than those
due to covalent bonds, or the electrostatic interaction
of ions with one another, with neutral molecules, or
with charged molecules. The term includes:
force between two permanent dipoles (Keesom Johannes Diderik van der Waals
Leiden, The Netherlands, 1837 -1923
force)
force between a permanent dipole and a
corresponding induced dipole (Debye force)
force between two instantaneously induced dipoles
(London dispersion force).
It is also sometimes used loosely as a synonym for the
totality of intermolecular forces.
