Fundamental of Molecular Spectroscopy

During the writing of this, the third edition of Fundamentals of Molecular Spectroscopy, I have borne very firmly in mind the aims of the original book-to emphasize the overall unity of the subject, and to offer a pictorial rather than a mathematical description of the principles of spectroscopy. The latter aim has received some criticism (although, it must be said, from teachers of the subject rather than from those trying to learn it); but, while it is true that universities and polytechnics now offer excellent courses in subjects such as quantum mechanics, a grasp of which can illuminate many areas of spectroscopy, experience shows that most students approaching spectroscopy for the first time prefer the simpler treatment offered here.

The general organization of the book remains unchanged, each chapter after the first presenting the fundamentals of a particular spectroscopic technique. Although each chapter is thus essentially self-contained, the in- tention is that the book shall be read as a whole, since concepts introduced in early chapters are often used later without further discussion.

In fact, although it is an almost unbelievable ten years since the second edition was published, there has been relatively little change in the basic ideas of spectroscopy, and much of the book is essentially unaltered. What changes have occurred have been mainly in the extension of existing tech- niques, and their increasing availability due to improvements in instrumen- tation. In this respect the two main areas of interest are the use of lasers as radiation sources, and the very rapid expansion in the use of Fourier trans- form techniques. Accordingly I have added a section on lasers to Chapter 1 and expanded the references to them in later chapters, particularly in Chap- ter 3. Equally, a general description of the Fourier transform method has been included in Chapter 1, and Chapter 7 has been extensively rewritten to take account of the wealth of additional information accessible from the application of this technique to nuclear magnetic resonance spectroscopy.

When a book has been in use for 15 years it becomes impossible to acknowledge the help received from the very many people, students and teachers, who have commented on it. My greatest debt is, of course, to Professor Sheppard of the University of East Anglia, who first introduced me to the beauty and fascination of spectroscopy, but I hope that all those who see their comments and suggestions incorporated into this edition will accept this general acknowledgement of my indebtedness, and will not think me churlish for leaving them unnamed.
