Fig. 1. Schematic representation of (a)
the dipolar interaction between
parallel permanent dipoles, (b) a
permanent and an induced dipole, and
(c) the dispersion interaction between
two helium atoms.
The dispersion interaction energy of a pair of isotropic molecules with ionization energies
hv 1and hv 2, separated by a distance r is given by:
