Full Text fundamentally different from other optical techniques. It is in essenceboth a calorimetric technique as well as a form of optical spectroscopy. This book has five chapters on gases covering theory, system design, and de-excitation studies. Five chapters are also devoted to the condensed phase, including a detailed theory of the gas-microphone signal in particular. The remaining thirteen chapters is a miscellany of applications of PAS in such diverse fields as chemistry, biology, and medicine.
Recent experiments on low temperature studies, surface studies, and thickness measurements are described and there is a final chapter on photo-acoustic microscopy PAM. Many of the chapters are very brief but do give sufficient bibliography to enable further reading. The book is well illustrated and the mathematics is straightforward. The author does discuss future trends and is somewhat optimistic about the potential and capabilities of PAS.
Nevertheless PAS is an established research technique but commercial prospects seem to be less good until a more quantitative scale is available for the PAS signal. Parke Fundamentals of Chemistry. Brady and J. Wiley, Chichester. Hard cover f Paperback f8. This is a comprehensive text-book of chemistry written for first-year university students in the U. The authors, assuming limited preparation, particularly in mathematics, have used simple algebra, and have added a brief mathematical appendix including the use of electronic calculators.
Each chapter is carefully constructed with marginal notes, worked exercises, examples, review questions, and a concluding summary. A mixture of SI and traditional metric units has been chosen, but there is ample guidance on their interconversion, and values are listed in both systems The book is beautifully produced, contains a page glossary of technical terms, and a separate index. It can be read with profit and pleasure by experienced chemists, and should be particularly useful to students at the transition from school to higher education for whom chemistry is not their final objective.
Couper OrganicPhotochemistry. Editedby AlbertPadwa. Dekker, New York. The fifth volume in this series places more emphasis on the synthetic applications of organic photochemistry than previous volumes and contains five chapters which review areas that have been advanced in recent years.
The first chapter deals with the mechanism the applications of and synthetic Paterno-Buchi reaction. It is well written and has many interesting general comments. It provides a good background to the understanding of these often complex reactions and should provide the reader with useful predictive ability.
The third chapter reviews current literature in the area of photoextrusion reactions limited to those processesin which the small molecule to be expelled is initially part of a ring with the remaining fragment forming a ring. By classifying reactions on the basis of the small molecular fragment expelled, the author presents his information in a clear, concise form. Chapter 4 describes recent research relating to the Norrish type 1 reaction of cycle-alkanones in solution and is mainly concerned with the mechanism of the reaction and substituent effects.
The final article reviews recent research on aliphatic and alicyclic imides and phthalimides. The entire volume will be useful for organic chemists with some knowledge of photochemistry as well as specialists. Every chapter cites references up to mid and the presentation is clear and contains very few errors. Williams SuccessinOrganicChemistry. ByMalcolm Hawkins. John Murray, London. Paperback, f3. The text, which assumes O-level or equivalent knowledge of chemistry, is aimed at a wide readership including A-level Chemistry and Technician Education Council Levels II and III diploma course students as well as anyone who, for whatever reasons, simply wishes to acquire a basic understanding of organic chemistry.
The well-chosen and clearly-illustrated subject matter is presented as twenty-one units, each of which has most worthwhile self-testing questions with answers and also included in many sections are tried and tested illustrative experiments requiring the simplest of apparatus. The text is written in a clear, logical manner, and is well-indexed.
The comments throughout the book concerning the relevance of the various reactions and the uses of particular compounds should awaken if necessary and ensure continued student interest in the subject. There is little doubt that students who rigorously apply the brief instructions given in the preface, will derive the maximum benefit from the text and, at the end of this essentially self-taught course, will have an excellent appreciation of basic organic chemistry.
In summary, the book should prove of great value to its broadly-based intended readership and at the realistic price of f3. Gilbert IonicLiquids. EditedbyDouglaslnmanand DavidG. Plenum, New York. It contains 20 chapters on a large number of topics and explains the reasons behind much of the current interest in ionic liquids.
The book demonstrates that these systems are fundamental to many aspects of everyday life and they will become increasingly important in an advanced technological society. There are chapters on new electrolyte materials, molten salt batteries, the electro-winning of metals, and Dead Sea brines, all of which are discussedin depth and present a clear idea of what is currently known, as well as the many fascinating problems which remain.
There are several articles on the fundamental properties of ionic liquids as determined by a variety of modern techniques: for example, neutron diffraction and the methods of computer simulation. Unfortunately, the value of this book would have been greatly enhanced if the chapters had been arranged in a more logical manner and the index had been more comprehensive.
As it is, most topics are cited only once and there is virtually no cross referencing. However, the book is a timely and welcome addition to this subject and will be of use to pure and applied scientists interested in the principles and practice of molten-salt technology. Neilson AdvancesinPhysiologicalSciences,Vol. Hutasand L. The tenth volume consists of selected papers in respiration presented at the 28th International Congress of Physiological Sciences held in Budapest, Hungary, The reader will appreciate the many charts, graphs, and diagrams which are extremely useful in organizing and understanding the text material.
