This book covers the broad area of spectroscopic analysis of microquantities of organic materials. ft summarises the advances made since 1968 and attempts to define sample size limitations for over 20 forms of spectroscopy. The book is of value to analytical, research and industrial chemists who wish to gauge the limitations of various spectroscopic techniques_ For students, the book clearly presents the modern' aspects of spectroscopic organic microanalysis. The author covers six broad categories of instrumental analyses which include mass spectrometry; infrared, ultraviolet and raman spectroscopy; nuclear magnetic resonance; optical rotatory dispersion and circular dichroism. For each of these topics, sample purification and handling techniques are thoroughly discussed. The author provides, in addition, brief sections regarding the interpretation of data and the use of ancillary techniques to improve or extend the data. When instrumental modifications are practical, the author briefly describes them and gives their limitations_ The ancillary techniques discussed include thin-layer and gas chromatography. Much attention is given to the use of gas chromatography for sample pu&cation 2s well 2s for sample introduction into varidus spectrometers. The section on multiple column gas chromatography is of particular interest. The book is well written and fully documented. The majority of sources cited are recent and easily obtained. In the areas of Fourier transform infrared and nuclear magnetic resonance spectroscopies, the author does 2 good job with the more recent advances clearly delineated. However, in the area of computerisation of mass spectral data, some of the more recent advances have been neglected. The author has drawn together the isolated areas of spectroscopic microanalyses and has set forth the general factors which influence these analyses. The analytical problems included are those of current interest, e.g., pesticides, alkaloids and essential oils. The author fairly states instrumental limitations and advantages for several manufacturers. The book is a good brief review of 2 difficult subject. Jt convers the v2rious instrumental techniques most adequately for those who wish a general view, while for the serious analyst, the work is well documented.
