This was first described by its namesake in 1930, using a quantum mechanical theory based on second-order perturbation theory.

According to this explanation, no intermolecular antisymmetrization of the electronic states is included, and the Pauli exclusion principle is only partially satisfied. Looking at the effects of this, it has been found that although for highly polar molecular pairs such as H2O-H2O the effect of this only accounts for 24% of the total energy interaction, for the most part, as with HBr-HBr and Ne-Ne pairs, the effect of this makes it the dominant of the three Van der Waals forces. This force is present between all chemical groups, but is generally weaker than ionic and hydrogen bonds; however, without this there would be no attractive force between noble gas atoms. FTP, what is this type of dispersion force that becomes stronger with increasing surface area, a weak intermolecular force arising from quantum-induced instantaneous polarization multipoles in molecules, named after a certain German-American physicist?
