This book is not intended to be a basic text in infrared spectroscopy. Many such books exist and I have referred to them in the text. Rather, I have tried to find applications that would be interesting to a variety of people: advanced undergraduate chemistry students, graduate students and research workers in several disciplines, spectros copists, and physicians active in research or in the practice of medicine. With this aim in mind there was no intent to have exhaustive coverage of the literature. I should like to acknowledge my use of several books and reviews, which were invaluable in my search for material: G. H. Beaven, E. A. Johnson, H. A. Willis and R. G. 1. Miller, Molecular Spec troscopy, Heywood and Company, Ltd., London, 1961. J. A. Schell man and Charlotte Schellman, 'The Conformation of Polypeptide Chains in Proteins," in The Proteins, Vol. II, 2nd Ed. (H. Neurath, ed.), Academic Press, New York, 1964. R. T. O'Connor, "Application of Infrared Spectrophotometry to Fatty Acid Derivatives," J. Am. Oil Chemists' Soc. 33, 1 (1956). F. L. Kauffman, "Infrared Spectroscopy of Fats and Oils," J. Am. Oil Chemists' Soc. 41,4 (1964). W. J. Potts, Jr., Chemical Infrared Spectroscopy, Vol. I, Techniques, Wiley, New York, 1963. R. S. Tipson, Infrared Spectroscopy of Carbohydrates, National Bureau of Standards Monograph llO, Washington, D.C., 1968. C. N. R. Rao, Chemical Applications of Infrared Spectroscopy, Academic Press, New York, 1963.

This volume includes spectroscopic methods for the characterization of macromolecules. Methods span the electromagnetic spectrum from X-ray to microwaves. It focuses on the types of information that can be derived: how measurements are made; state of the art apparatus; data acquisition, analysis, and interpretation; casebook examples; and new developments and future directions. Key Features * Ultraviolet and Visible Spectroscopy, including * Absorption and Circular Dichroism * Transient Absorption and Kinetics * Linear Dichroism and Fluorescence * Vibrational Spectroscopy * Magnetic Resonance Spectroscopy * X-Ray Spectroscopy

Fluorescence spectroscopy has traditionally found wide application in bio chemistry and cell biology. Since there are relatively few naturally occurring fluorescent biomolecules, fluorescence spectroscopy offers a combination of great specificity and sensitivity. Historically, these features have been ex ploited with great success utilizing both intrinsic and extrinsic probes. Re cent applications have built upon these traditional strengths and have re sulted in the development of new instrumental techniques, novel and convenient fluorescent probes, and a deeper, theoretical understanding of fundamental processes. Frequently, fluorescence techniques are tailored to attack a specific biological problem. These new methods in turn produce new physical situations and phenomena which are often of interest to the physical chemist. Thus, progress in one area stimulates renewed interest in other areas. The goal of this book is to provide detailed monographs on the use of fluorescence to investigate problems at the forefront of biochemistry and cell biology. This book is not meant to be a comprehensive survey but rather to highlight areas of recent developments. It is designed to be readable to the novice and yet provide sufficient detail for the expert to keep abreast of recent developments. The book is organized so that it proceeds from simple biochemical sys tems to more complex cell biological ones. Chapter I on fluorescence quenching of biological structures is a good introductory chapter. It intro duces a number of elementary concepts and discusses applications to pro teins and biomembranes.

This book has been written in part with the aim of providing a text which will be useful in teaching the biochemical applications of spectroscopy. This book will be of particular use to the biochemist or biologist who does not have a background in spectroscopy, but desires to find out what sort of information spectroscopy can provide. Attention was limited to those techniques most frequently used, and which at present have the widest applications.

The technique of nuclear magnetic resonance (NMR) spectroscopy is an important tool in biochemistry and biophysics for the understanding of the structure and ultimately, the function of biomolecules. This textbook explains the salient features of biological NMR spectroscopy to undergraduates and postgraduates taking courses in NMR, biological NMR, physical biochemistry, and biophysics. Unlike other books in the general field of NMR (except the advanced treatises), the approach here is tointroduce and make use of quantum mechanical product operators as well as the classical vector method of explaining the bewildering array of pulse sequences available today. The book covers two- dimensional, three- dimensional, and four- dimensional NMR and their application to protein and DNA structure determination. A unique feature is the coverage of the biological aspects of solid- state NMR spectroscopy. The author provides many selected examples from the research literature, illustratingthe applications of NMR spectroscopy to biological proteins.
