The long and intermediate range interaction between a metal surface and an external molecular complex is investigated. The calculation is based on a simplified model where the complex is represented by an ensemble of point multipole fields and the metal by a semi‐infinite jellium of smeared out ionic cores and free electrons. The response of the metal electrons to the external field is obtained in closed form by a linearized Thomas‐Fermi treatment. The energy of the complex in the metal surface response field is determined from perturbation theory. Applications to the effective multipole moments of the complex and to the changes in its internal couplings are discussed.
