Quantum mechanics central force problem

Generalization of quantum mechanics to D spatial dimensions is illustrated explicitly for a few elementary examples. For central force problems the sole effect is to augment the orbital angular momentum by I I + — 3). As shown by Rost, this relation holds even for... 

Slater was one of the first scientists to realize that in qualitative discussions of molecule formation, the best procedure to follow was to compare critically the results of the two different methods developed—the valence bond and the molecular orbital viewpoint, and to point out, as already mentioned, that the choice between the two should be made on the basis of convenience rather than correctness. However, in Introduction to Chemical Physics, just a few lines are devoted to such a central topic in the context of Slater s contributions to quantum chemistry as well as in the development of the discipline itself. In the chapter on "Interatomic and Intermolecular Forces," in the section about "Exchange Interactions Between Atoms and Molecules," Slater stated that the problems of quantum chemistry are among the most complicated of quantum theory and that the theory itself will not be treated in an analytical manner. He considered the Heider-London approach and the molecular orbital approach as two different approximate methods of calculation used in wave mechanics. He believed that these two methods do not differ in their "fundamentals, but in the precise nature of the analytical steps used." And he proposed to study "the fundamental physical processes behind the intermolecular actions and we shall find that...
