After a brief discussion of the deformation of the ground‐state electron density asymptotically, in free space homonuclear diatomics by dispersion interactions, dimers in dense homogeneous plasma will be treated. Polarization interaction will be shown to lead to an R −4 interaction energy at large internuclear separation, R , supplementing the well‐known long‐range oscillatory interaction. The relevance of these interactions, when suitably modified for a heterogeneous environment, to lateral forces between CO molecules chemisorbed on a transition metal surface will then be considered, with specific reference to experiments on thermal desorption. Finally, the theory of the inhomogeneous electron liquid in intense magnetic fields will be briefly discussed, for both localized and delocalized electrons. © 1992 John Wiley & Sons, Inc.
