REVIEW OF QUANTUM MECHANICS

The main aim of this chapter is to obtain the form of the wavefunctions which describe atomic energy levels. These wavefunctions will be essential in our discussion of radiation processes in later chapters. We start by introducing Schrodinger s equation and summarize some of the operations which are fundamental to quantum mechanics. We then show how the angular part of Schrodinger s equation can be solved exactly in the case of spherically symmetric potentials.

This section provides an overview and review of quantum mechanics calculations. The information can help you use Hyper-Chem to solve practical problems. For quantitative details of quantum mechanics calculations and how HyperChem implements them, see the second part of this book. Theory and Methods. 

In this chapter, a brief review of quantum mechanical methods and the arrangement of electrons in atoms has been presented. These topics form the basis for understanding how quantum mechanics is applied to problems in molecular structure and the chemical behavior of the elements. The properties of atoms discussed in Chapter 1 are directly related to how the electrons are arranged in atoms. Although the presentation in this chapter is not exhaustive, it provides an adequate basis for the study of topics in inorganic chemistry. Further details can be found in the references.

The Zeeman effect in L-S coupling. Finally in this review of quantum mechanics we recall that every circulating current I in classical electromagnetism possesses a magnetic moment, determined by the product of I and the area of the current loop. Similarly in the atom there exists a magnetic moment associated with the orbital motion of the electron where is given by the quantum mechanical operator...
