Applications of the Theory of Continuous Groups,ustrate the possibilities of the theory with some examples. We cannot give a complete discussion of all symmetry groups used in modern particle physics. Rather, we show with some examples how to employ some groups, ℒ .. ⩽5, in modern physics and how to work with mechanisms of symmetry breaking. The

Representations of Finite Groups,essential ones. The basic spaces are the linear (vector) spaces, which are discussed first in this chapter. Then the properties of different representations are outlined with special emphasis on the irreducible ones. Finally we investigate product representations of groups.

Molecular Spectra,ted in the following, starting with the vibrational states (including infrared absorption and Raman effect), then discussing the properties of one-electron approximations (hybridization, Hückel method, ligand field theory) and finally by considering many-electron problems.

Selection Rules and Matrix Elements,tive transitions between different energy levels, the splitting of energy levels in a crystalline field and the Stark and Zeeman effects. Section 8.5 deals with the determination of independent components of a material tensor (a tensor describing physical properties).

Excitation Spectra and Selection Rules in Crystals,ons) and electronic excitations for which we discuss the symmetrized eigenvalue problem. Finally we study the selection rules for the electron-phonon, electron-photon and phonon-photon interactions in crystals, including infrared absorption and the Raman effect.

Representations by Young Diagrams. The Method of Irreducible Tensors,ble tensors of rank .Ψ. withƒ= {ƒ.,… ,ƒ.}. This description of the IRs of continuous groups is quite different from the Lie-Cartan-Weyl method; it supplements the latter. In order to illustrate this, we recall the method for finding the basis tensors.
