Fundamentals of Molecular Symmetry
- Book Review,
by P.R. Bunker
From Book News, Inc.
Bunker (Steacie Institute for Molecular Sciences) and Hensen (Bergische University Wuppertal) explain the role symmetry plays in the solution of problems in spectroscopy and molecular orbital theory. Their graduate textbook focuses on the relationship between the geometrical symmetry of a molecule, as expressed using the point group symmetry of it equilibrium structure, and the true symmetry of a molecule, as expressed using the molecular symmetry group.

Book Description
Molecular symmetry is an easily applied tool for understanding and predicting many of the properties of molecules. Traditionally, students are taught molecular symmetry using point groups derived from the equilibrium geometry of the molecule. However, the true basis for molecular symmetry is not geometrical symmetry, and this book shows how to set up symmetry groups for molecules using more fundamental ideas. It is no more difficult than doing it using molecular geometry, and one obtains Molecular Symmetry (MS) groups. Point group symmetry is derived by approximation from MS group symmetry. The approach taken gives a balanced account of both types of symmetry group. Usually the point group is only useful for isolated, nonrotating molecules, executing small amplitude vibrations in isolated electronic states. However, for the chemical physicist or physical chemist who wishes to go beyond these limitations, the MS group is nearly always required. An introductory description of molecular spectroscopy and quantum mechanics is given in order that the book be self- contained in describing how molecular symmetry is to be understood and used. The book is suitable for both undergraduates and research students in molecular science
