Symmetry Principles in Solid State

High-level text applies group theory to solid state and molecular physics. The author develops short-cut and invariant methods for solving molecular vibration problems and for determining the form of crystal tensors; develops the translational properties of crystals, including Bravais lattices and space groups; and explains relevant applications to electron phonon scattering, optical absorption selection rules, electronic energy bands, electron dynamics, and effective Hamiltonians. Unique features of this volume include use of subgroup techniques, consideration of the influence of time reversal on selection rules, use of shell theorems and invariance techniques to construct the form of tensors, and use of broken symmetry to relate the symmetry of valence and molecular orbitals to the symmetry of electron molecular wave functions. 1974 edition. More than 200 problems. 69 black-and-white illustrations. Eight appendixes. Author Index and Bibliography. Indexes.
