Infrared Spectroscopy


Book Description

It is estimated that there are about 10 million organic chemicals known, and about 100,000 new organic compounds are produced each year. Some of these new chemicals are made in the laboratory and some are isolated from natural products. The structural determination of these compounds is the job of the chemist. There are several instrumental techniques used to determine the structures of organic compounds. These include NMR, UV/visible, infrared spectroscopy, mass spectrometry, and X-ray crystallography. Of all the instrumental techniques listed, infrared spectroscopy and mass spectrometry are the two most popular techniques, mainly because they tend to be less expensive and give us the most structural information. This book is an introductory text designed to acquaint undergraduate and graduate students with the basic theory and interpretative techniques of infrared spectroscopy. Much of the material in this text has been used over a period of several years for teaching courses in materials characterization and chemical analysis. It presents the infrared spectra of the major classes of organic compounds and correlates the infrared bands (bond vibrations) of each spectrum with the structural features of the compound it represents. This has been done for hydrocarbons, organic acids, ketones, aldehydes, esters, anhydrides, phenols, amines, and amides. The text discusses the origin of the fragments, techniques, innovations, and applications in infrared spectroscopy. It is interspersed with many illustrations, examples, an adequate but not overwhelming bibliography, and problems for students. It will serve as a lecture text for a one-semester course in infrared spectroscopy or can be used to teach the infrared spectroscopy portion of a broader course in material characterization and chemical analysis.




The Handbook of Infrared and Raman Characteristic Frequencies of Organic Molecules


Book Description

This necessary desk reference for every practicing spectroscopist represents the first definitive book written specifically to integrate knowledge about group frequencies in infrared as well as Raman spectra. In the spirit of previous classics developed by Bellamy and others, this volume has expanded its scope and updated its coverage. In addition to detailing characteristic group frequencies of compounds from a comprehensive assortment of categories, the book includes a collection of spectra and a literature search conducted to verify existing correlations and to determine ways to enhance correlations between vibrational frequencies and molecular structure. Particular attention has been given to the correlation between Raman characteristic frequencies and molecular structure. - Constitutes a necessary reference for every practicing vibrational spectroscopist - Provides the new definitive text on characteristic frequencies of organic molecules - Incorporates group frequencies for both infrared and Raman spectra - Details the characteristic IR and Raman frequencies of compounds in more than twenty major categories - Includes an extensive collection of spectra - Compiled by internationally recognized experts







Introduction to Infrared and Raman Spectroscopy


Book Description

Now in its third edition, this classic text covers many aspects of infrared and Raman spectroscopy that are critical to the chemist doing structural or compositional analysis. This work includes practical and theoretical approaches to spectral interpretation as well as a discussion of experimental techniques. Emphasis is given to group frequencies, which are studied in detailed discussions, extensive tables, and over 600 carefully chosen and interpreted spectral examples. Also featured is a unique treatment of group frequencies that stresses their mechanical origin. This qualitative approach to vibrational analysis helps to simplify spectral interpretation.Additional topics include basic instrumental components and sampling techniques, quantitative analysis, Raman polarization data, infrared gas contours, and polarized IR studies, among others. - Focuses on group frequency correlations and how to use them in spectral interpretation - Revised and updated by a pioneer in the field, Norman Colthup, who for thirty years has served as an expert lecturer for the Fisk Infrared Institute - Explores new group frequency studies in aromatics, alkanes and olefins, among others - Includes completely updated section on instrumentation







Fourier Transform Infrared Spectroscopy


Book Description

This volume is a collection of contributions to the FT-IR Workshop held under the auspices of the Spectroscopy Society of Canada and organ ized by Professor Theophile Theophanides, Director of the Workshop. The gathering of leading spectroscopists and researchers at Gray Rocks to discuss .Fourier Transform Infrared Spectroscopy was the occasion of the 29th Annual Conference of the Spectroscopy Society of Canada. The plea sant surroundings of Gray Rocks, St-Jovite, Quebec, Canada contributed most positively to the success of the two-day Workshop held September 30, October 1, 1982. The preliminary program and the proceedings were distributed at the Workshop by Multiscience Publications Ltd. The publication of this volume provides the occasion to thank all the contributors for kindly accepting to lecture at the Workshop and for their collaboration. I thank Mr. AI. Dufresne for accepting to act as manager of the Workshop and Mrs. Susane Dufresne secretary of the Work shop for patiently contacting all the participants and for making the necessary arrangements of registration and accomodation.

Interpreting Infrared, Raman, and Nuclear Magnetic Resonance Spectra


Book Description

This book teaches the analyst why it is advantageous to obtain vibrational data under different physical phases. Molecular vibrations are affected by change in physical phase, and knowledge of how certain molecular vibrations are affected by change in the chemical environment improves the analyst's ability to solve complex chemical problems. This book is invaluable for students and scientists engaged in analytical and organic chemistry, since application of IR and Raman spectroscopy is essential in identifying and verifying molecular structure. This reference provides analysts with information that enables them to acquire the maximum amount of information when sampling molecular vibrations via IR and Raman spectroscopy. Key Features * Explains why it is advantageous to obtain vibrational data under different physical phases * Compiles many vibrational studies into a single compendium * Lists group frequencies in different physical phases * Reveals that some group frequencies are more affected than others by changes in the physical phase * Demonstrates that in-phase and out-of-phase vibrations of the same functional group are not equally affected * Describes how solute-solvent complexes differ with changes in the solvent system * Shows that the amount of Fermi resonance between a fundamental vibration and a combination or overtone is altered with change of physical phase * Written by an internationally recognized expert
