✦ Synopsis

The dipole response of a cubic molecular crystal has two parts: the 'virtual' respnse is not excited by light; the 'rea1' response is, and is surface dependent. The virtual response is described by essentially two dielectric constants.

Results for the correction in the polarizability of an atom due to intermolecular dispersive interactions are presented for atomic hydrogen, considered as a typical example of non two-level atoms. A simple aporodmation scheme, which is useful for more complicated systems and leads to excellent resul
