Dipole–dipole interaction is between polar molecules. A polar molecule has an electric dipole moment by virtue of the existence of partial charges on its atoms. Opposite partial charges attract one another, and, if two polar molecules are oriented so that the opposite partial charges on the molecules are closer together, then there will be a net attraction between the two molecules with a potential energy V given by

μ_i are the dipole moments

ε is the permitivity of the medium

T is the temperature in Kelvin
