Abstract

The dispersion interaction between two nonoverlapping atoms (or molecules) is expressed in terms of single‐atom “polarizabilities.” The formulation is valid even if one atom (or both) is in an excited state. To illustrate the procedure, the dispersion interaction between a 1__s__ and a 2__s__ hydrogen atom is computed accurately through order R^−10^ (R = internuclear separation).
