The Spectra and Structures of Simple Free Radicals


Book Description

"Authoritative and clearly written."—Applied Optics The direct observation of short-lived free radicals and the consequent study of their structure and reactions have led to important developments in almost every branch of chemistry as well as in other areas. This volume by a Nobel laureate offers an excellent introduction to the essentials of molecular spectroscopy. The introductory chapter discusses experimental methods and illustrates the observed spectra of various molecules and free radicals. Subsequent chapters explore rotational, vibrational, and electronic energy levels of diatomic molecules and ions; radiative transitions; linear and nonlinear polyatomic radicals and ions; continuous and diffuse spectra; predissociation and pre-ionization; and recombination. The well-illustrated text features more than 100 figures and spectra. A distilled version of the author's monumental three-volume study, Molecular Spectra and Molecular Structure, it constitutes a superb resource for anyone wishing a concise but complete treatment of the fundamentals of molecular spectroscopy.




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







Molecular Spectra and Molecular Structure - Vol I


Book Description

“I have endeavoured to give a presentation which is readable by the beginner in the field and also will be useful to those who do or want to do research work in this field. In order to assist the former, I have frequently made use of small type for those sections that are not necessary for an understanding of the fundamentals. For the benefit of those working in the field, numerous references to original papers have been included. “A satisfactory presentation of molecular spectra and molecular structure is nowadays not possible without treating thoroughly, apart from the empirical results, the theoretical background also. Therefore, I have included as much of the theory of molecular spectra as is possible without going into the more difficult mathematical details. A large number of diagrams, graphical representations of eigenfunctions and potential curves, as well as energy level diagrams, serve to illustrate and to explain the theory. On the other hand, I have added numerous carefully selected spectrograms of bands and band systems (some of which have been taken specially for this purpose) in order to give an accurate idea of the experimental material that forms the basis of the developments.
