Part of the Springer Series in Solid-State Sciences book series (SSSOL, volume 64)


In the preceding section we developed the methods necessary for a discussion of space group symmetries in crystals. In the following we apply these methods to an investigation of the elementary excitations in crystals, which have many aspects in common. Among these there are phonons (lattice vibrations) 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.
