The potential energy function for the force between two atoms in a diatomic molecule is approximately given by

U\left( x \right) = {a \over {{x^{12}}}} - {b \over {{x^6}}},

where

a

and

b

are constants and

x

is the distance between the atoms. If the dissociation energy of the molecule is

D = \left[ {U\left( {x = \infty } \right) - {U_{at\,\,equilibrium}}} \right],\,\,D
