These interactions are responsible for the sixth power term in the Lennard-Jones potential, andusing a multipole expansion followed by the Unsold approximation allows the introduction ofionization potentials to explain it.

The strength of these interactions is proportional to the product ofthe polarizability volumes, and these interactions are the reason that heavier halogens are liquids andsolids and lighter ones are (*) gases. The strength of these interactions increases with the size of the atomsinvolved because larger electron clouds can form dipoles more easily. For 10 points, name this weakintermolecular force, a subset of van Der Waals forces between instantaneous dipoles.
