The first two terms make up the electronic kinetic energy and the next two the electron–nucleus attraction. The interelectronic repulsion term,, prevents use of the separation of variables technique of section Therefore, exact solutions for He or any other system with two or more electrons cannot be obtained; finding approximate ones is the central task of quantum chemistry.

Hückel established a remarkably useful model for the characterization of. Perturbation theory is a method for continuously improving a previously obtained approximate solution to a problem, and it is an important and general method for finding approximate solutions to the Schrödinger equation.

We discussed a simple application of the perturbation technique previously with the Zeeman effect. The book does not presume to cover all aspects of many-body theory.

Only many-electron systems are considered, but the techniques described apply equally well to all many-fermion systems, and, with slight modifications, to many-boson systems also. Mel Levy and Elliott Lieb are two of the most prominent researchers who have dedicated their efforts to the investigation of fundamental questions in many-electron theory.

Their results have not only revolutionized the theoretical approach of the field, but, directly or indirectly, allowed for a quantum jump in the computational treatment of realistic systems as well.

For this reason, at the Cited by: 1. Einstein proposed his theory of special relativity in For a long time it was believed that this theory has no significant impact on chemistry.

This view changed in the s when it was realized that (nonrelativistic) Schrödinger quantum mechanics yields results on molecular properties that depart significantly from experimental results.

Especially when heavy elements are involved. Considering the chapters of this book as a road-map for the progress in the field of many-electron theories along the path of multi-disciplinarity, one can draw some basic conclusions.

It is clear that computational physics and chemistry are going to have a role of increasing importance in the description of many-electron systems, as. Introduction to Elementary Molecular Orbital Theory and to Semiempirical Methods.
