Jahn-Teller effect For all those chemists whose understanding of the Jahn-Teller effect involved explaining why 6-coordinate copper(II) complexes are never regular octahedra, or why the U.V./visible spectra of octahedra l titanium(III) complexes show a shoulder on the side of the main peak, this text is a real eye opener. It is certainly a book for the purists, but it does cover aspects of physics, chemistry and biology. It treats the subject at a high level, and employs quite a rigorous mathematical approach.

For the general reader Chapter 1 is very helpful, as in it the author provides a general historical introduction to the subject; explains the general principles, putting Jahn-Teller vibronic coupling effects in the context of molecul ar and array structural science; and outlines the aims and objectives of the book.

In Chapter 2 the fundamental physics leading to the development of the theory are explained, while in Chapter 3 the basic formulations for different symmetry systems are discussed and the methods used to deal with multicentre systems explained. In Chapter 4 pseudo-Jahn-Teller, product Jahn-Teller and Renner-Teller (which deals with linear molecules) effects are discussed. In Chapter 5 the solutions to the vibronic equations are described, as are the energy spectra showing dynamic Jahn-Teller effects. In Chapter 6 the general theory relating to electronic spectra, infrared and Raman spectra and magnetic resonance spectra is covered. In Chapter 7 the geometry and spectra of molecular systems ranging from diatomics up to pentaatomic MX4 systems, and benzene and cyclopentadienyl families, are discussed. Finally, in Chapter 8, Jahn-Teller effects in solid-state systems are described.

This is probably not a book that a crystallographer would sit down and read cover-to-cover but for the general reader this book is certainly useful as a reference volume, and for experts in the area the text would be a useful addition to a library. The material is very well and clearly presented, and it is apparent that the text has been written by an expert in the field. There are references at the end of each chapter which provides a useful source of the original literature and provides a source for further reading.
