Recent advances in infrared molecular spectroscopy have resulted in sophisticated theoretical and laboratory methods that are difficult to grasp without a solid understanding of the basic principles and underlying theory of vibration-rotation absorption spectroscopy. Rotational Structure in Molecular Infrared Spectra fills the gap between these recent, complex topics and the most elementary methods in the field of rotational structure in the infrared spectra of gaseous molecules. There is an increasing need for people with the skills and knowledge to interpret vibration-rotation spectra in many scientific disciplines, including applications in atmospheric and planetary research. Consequently, the basic principles of vibration-rotation absorption spectroscopy are addressed for contemporary applications. In addition to covering operational quantum mechanical methods, spherical tensor algebra, and group theoretical methods applied to molecular symmetry, attention is also given to phase conventions and their effects on the values of matrix elements. Designed for researchers and PhD students involved in the interpretation of vibration-rotation spectra, the book intentionally separates basic theoretical arguments (in the appendices), allowing readers who are mainly concerned with applications to skip the principles while at the same time providing a sound theoretical basis for readers who are looking for more foundational information. Reviews basic theory and contemporary methods of vibration rotation absorption spectroscopy, including operational quantum mechanical methods, spherical tensor algebra, and group theoretical methods applied to molecular symmetry Covers sophisticated mathematical topics in simple, easy-to-read language Discusses methods and applications separately from basic theoretical arguments for quick reference

The accurate interpretation of infrared spectra of organic structures is an extremely important tool for the analytical chemist. Using up-to-date source material, this volume presents a compilation of the infrared absorption regions of ninety of the most important organic molecular fragments. This highly practical guide introduces the reader to a straightforward technique for determining all the fundamental vibrations of a molecular fragment. The set of normal vibrations and the infrared absorption regions of ninety molecular fragments are then discussed and tabulated. The discussion of each fragment is accompanied by a large number of references. A Guide to the Complete Interpretation of Infrared Spectra of Organic Structures offers the analytical chemist the possibility of a more profound interpretation of infrared spectra. In addition, it assumes only a basic knowledge of infrared spectra, and so will prove very useful for non-specialists who use infrared spectroscopy in analysis.

Recommendations for the Presentation of Infrared Absorption Spectra in Data Collections–A. Condensed Phases presents the recommendations related to the infrared spectra of condensed phase materials that are proposed for permanent retention in data collections. These recommendations are based on two reports published by the Coblentz Society. This book emphasizes the three levels of quality evaluation for infrared spectra as designated by the Coblentz Society, including critically defined physical data, research quality analytical spectra, and approved analytical spectra. This text discusses the criteria for spectrophotometer operation, including resolution, wavenumber accuracy, noise level, energy, and other performance criteria. This book is a valuable resource for applied chemists.

Tables of Wavenumbers for the Calibration of Infrared Spectrometers, Second Edition is a compilation of tables of wavenumber values for the calibration of infrared spectrometers. It makes the best use of high resolution results and integrates the far infrared data with the higher frequency values. This book is organized in two parts, one for high to medium-resolution spectrometers used by physical chemists and physicists, and the other for medium to low-resolution instruments employed by organic and inorganic chemists. The first part includes tables of wavenumber of infrared absorption lines in spectra of gaseous molecules as well as procedures for using the tables, including the calibration-curve method, the method of overlapping orders (superposition method), and atomic line method. The calibration tables are illustrated by infrared spectra obtained under a variety of conditions. The second part includes vapor, liquid, and solid phase calibrants for small spectrometers. This monograph will be a valuable resource for physicists, chemists, and spectroscopists.

The authors describe basic theoretical concepts of vibrational spectroscopy, address instrumental aspects and experimental procedures, and discuss experimental and theoretical methods for interpreting vibrational spectra. It is shown how vibrational spectroscopy provides information on general aspects of proteins, such as structure, dynamics, and protein folding. In addition, the authors use selected examples to demonstrate the application of Raman and IR spectroscopy to specific biological systems, such as metalloproteins, and photoreceptors. Throughout, references to extensive mathematical and physical aspects, involved biochemical features, and aspects of molecular biology are set in boxes for easier reading. Ideal for undergraduate as well as graduate students of biology, biochemistry, chemistry, and physics looking for a compact introduction to this field.
