The contribution of this interaction is given by the non-zero frequency term when summing over dielectric constants at imaginary frequencies with the McLachlan equation.
The contribution of this interaction is given by the non-zero frequency term when summing over dielectric constants at imaginary frequencies with the McLachlan equation. For objects with large radii of curvature, the strength of this interaction can be calculated in relation to its strength for planar surfaces by using the Derjaguin approximation. A correction for this interaction in three-body problems is given by the Axilrod-Teller potential. The finite speed of light causes a retardation effect in this interaction which is described in Lifshitz theory, and on macroscopic scales it is the major component of the Hamaker constant. (*) This force is the most significant component of a total force that also includes components named for Keesom and Debye. The strength of this force is proportional to polarizability and inversely proportional to the sixth power of distance, accounting for the attractive term in the Lennard-Jones potential. For 10 points, name this weak intermolecular interaction caused by instantaneous induced dipoles, one of the van der Waals forces.
