✦ Synopsis

A model relatmg the long-range dipoles of inert-gas heterodlatoms to the distortion of the electromc structure assonated urith dlsperslon forces is presented. Expressions are pven for the contriiutlons to the dipole varymg as the utverse seventh power of the atornx separahon R. The model 1s ako used to determine the long-range quadrupoles of homonuclear atomic paus Pau hyperpolanzabihtIes are obtamed m the model by adding contriiutions of classical multipolar mteractions and contributrons associated WIUI the distortion of the electronic structure. An independent test shows the consistency of the model and provides values for the effectwe mean-square dipoles and quadrupoles of the inert-gas atoms.
