This book looks at the common techniques used to prepare, purify and identify chemicals. Topics including distillation, recrystallisation, chromatography, elemental analysis, atomic absorption spectroscopy and mass spectrometry are discussed, and are illustrated on video on the accompanying CD-ROMs. Infrared and nuclear magnetic resonance spectroscopy are covered entirely through multi-media, with animations and virtual experiments. The reader is provided with examples for interpretation, and can draw in the structures using the software provided. There is also a set of interactive self-assessment questions. In all, the multi-media software suite comprises more than twelve hours of material. Separation, Purification and Identification concludes with a Case Study on Forensic Science, in which illustrations of criminal cases where spectroscopic techniques provided evidence are given. The Molecular World series provides an integrated introduction to all branches of chemistry for both students wishing to specialise and those wishing to gain a broad understanding of chemistry and its relevance to the everyday world and to other areas of science. The books, with their Case Studies and accompanying multi-media interactive CD-ROMs, will also provide valuable resource material for teachers and lecturers. (The CD-ROMs are designed for use on a PC running Windows 95, 98, ME or 2000.)

This book with its two companion CD-ROMs is the ninth in the series "The Molecular World." The editors state that the series aims to develop an integrated approach to chemistry with major themes in organic, inorganic, and physical chemistry. Using a combination of written exercises and material on the CD-ROMs, the book does an effective job of teaching the basic principles of separation techniques, purification, and spectroscopy. It is interesting that the workbook is used to teach separation and purification, with supplementary exercises on the CD-ROM, but the electronic medium is used exclusively for teaching spectroscopy. This approach gives readers a chance to evaluate the relative effectiveness of teaching using the written word versus electronic interactive media. On the basis of this work, there is little doubt that the electronic medium is superior. It makes one wish that the entire volume were taught on disc. The editors do an excellent job of using computers to teach the principles of spectroscopy. The book does not state at what level of reader it is aimed, but it is clear that this work is not for beginners. Readers must have a basic knowledge of chemistry before tackling this work. ^BSumming Up: Recommended. Upper-division undergraduate and graduate students; professionals. J. A.
