dc.descriptionThe Langevin theory of the polarization of a dilute collection of dipoles by an external field is often included in introductory solid state physics and physical chemistry curricula. The average polarization is calculated assuming the dipoles are in thermal equilibrium with a heat bath. The heart of the polarization calculation is a derivation of the average dipole-field projection, whose dependence on the external field is given by the Langevin function. The Langevin problem is revisited, here, and the average projection of any given dipole onto any other dipole from the collection is derived in terms of the Langevin function. A simple expression is obtained for the underlying dipole-dipole angular distribution function.
