Axilrod-Teller potential
Encyclopedia
The Axilrod–Teller potential is a three-body potential
that results from a third-order perturbation correction to the attractive London dispersion interactions
(instantaneous induced dipole-induced dipole)
where
is the distance between atoms 
and 
, and 
is the angle between the vectors
and 
. The coefficient 
is positive and of the order 
, where 
is the ionization energy and 
is the mean atomic polarizability; the exact value of 
depends on the magnitudes of the dipole matrix elements and on the energies of the 
orbitals.

Van der Waals force
In physical chemistry, the van der Waals force , named after Dutch scientist Johannes Diderik van der Waals, is the sum of the attractive or repulsive forces between molecules other than those due to covalent bonds or to the electrostatic interaction of ions with one another or with neutral...
