The Raman effect is a most useful tool for the study of molecular vibrations and molecular structure. Information about the structure and symmetry of molecules, as well as about their vibrational energies can be obtained to a reasonable degree of satisfaction from their infrared and Raman vibrational spectra. The body of knowl edqe of the vibrational infrared and Raman spectra of molecules is immense and is now so well organized and understood that it is found to be represented in any stan dard upper level undergraduate curriculum in chemistry. The rotational energies of a molecule and quantitative details about its structure can only be obtained through the techniques of microwave, and high-resolution infrared and Raman spectroscopy of low pressure gases and vapors. The results of such investigations are of interest . not only to the academic scientists, but also to scientists and engineers who are active in applied fields of chemistry and physics, as well as the atmospheric sciences. This book deals with basic investigations of the Raman scattering of light by gases, with some attention also being given to liquid substances. After a brief in troductory chapter that delineates the historical development of Raman spectroscopy of gases, high-resolution rotation-vibrational and pure rotational Raman spectros copy is described in Chapters 2 and 3. The all-important intensity parameter, the Raman scattering cross section, is treated in Chapter 4, while the broadening of Raman lines due to the effects of intermolecular forces is taken up in Chapter 5.

In recent years a number of non-linear Raman spectroscopic techniques have been substantially developed and are now proving to be powerful methods for the solution of many problems not only in spectroscopy but also in chemistry, physics and biology. These techniques include hyper Rayleigh and hyper Raman spectroscopy, coherent anti-Stokes Raman Spectroscopy (CARS), Raman Gain and In verse Raman Spectroscopy, Photoacoustic Raman Spectroscopy (PARS) and the Raman Induced Kerr Effect (RIKE). Hyper Raman spectro scopy although experimentally difficult is valuable for investi gating transitions which are not active in the infrared or in the linear Raman effect; and the other non-linear Raman effects can provide signal strength and resolution which are orders of magni tude higher than those obtainable with linear Raman spectroscopy. The thirty chapters in this book will form the basis of lectures presented at the NATO Advanced Study Institute in Bad Windsheim, F. R. Germany from August 23 - September 3, 1982.

Introduction to Infrared and Raman Spectroscopy focuses on the theoretical and experimental aspects of infrared and Raman spectroscopy, with emphasis on detailed group frequency correlations and their vibrational origin. Topics covered include vibrational and rotational spectra, molecular symmetry, methyl and methylene groups, triple bonds and cumulated double bonds, and olefin groups. Aromatic and heteroaromatic rings are also considered, along with carbonyl compounds and molecular vibrations. This book is comprised of 14 chapters and begins with a discussion on the use of Raman and infrared spectroscopy to study the vibrational and rotational frequencies of molecules, paying particular attention to photon energy and degrees of freedom of molecular motion. The quantum mechanical harmonic oscillator and the anharmonic oscillator are described. The next chapter focuses on the experimental techniques and instrumentation needed to measure infrared absorption spectra and Raman spectra. Symmetry is then discussed from the standpoint of the spectroscopist. The following chapters explore the vibrational origin of group frequencies, with an emphasis on mechanical effects; spectra-structure correlations; and the spectra of compounds such as ethers, alcohols, and phenols. The final chapter demonstrates how the frequencies and forms of a nonlinear molecule's normal modes of vibration may be calculated mathematically. This monograph will be a useful resource for spectroscopists and physical scientists.

This book covers the recent NMR studies with the application of gaseous molecules. Among the comprehensively discussed aspects of the area it includes in particular: new multinuclear experiments that deliver spectral parameters of isolated molecules and provide the most accurate values of nuclear magnetic shielding, isotropic spin–spin coupling and relaxation times; advanced, precise and correct theoretical descriptions of spectral parameters of molecules as well as the application of gas-phase NMR measurements to chemical analysis and medicine. The progress of research in these fields is enormous and has rapidly changed our knowledge and understanding of molecular parameters in NMR spectroscopy. For example, accurate studies of the shielding for isolated molecules allow the exact determination of nuclear magnetic dipole moments, the calculated values of spectral parameters can be verified by precise gas-phase NMR measurements, and the application of hyperpolarized noble gases provides excellent MRI pictures of lungs. Aimed at graduates and researchers in spectroscopy, analytical chemistry and those researching the applications of NMR in medicine, this book presents the connections between sophisticated experiments, the theory of magnetic parameters and the exploration of new methods in practice.

Minimaler Aufwand bei der Probenvorbereitung, hoher Informationsgehalt des Spektrums und die Möglichkeit, mit festen Proben zu arbeiten, machen die Raman-Spektroskopie zunehmend attraktiv. Wie man diese Methode mit modernster Ausrüstung effizient anwendet, zeigt Ihnen das vorliegende Buch. Im Mittelpunkt stehen neue Entwicklungen wie CCDs, Diodenlaser und Fourier-Transform-Techniken. Behandelt werden auch quantitative Analysen, die in der bisher vorhandenen Literatur häufig zu kurz kamen. (08/00)

Raman and Infrared (IR) spectroscopy supply complementary images of the vibrational spectra of molecules and crystals. IR, in particular, has long been used for the structure elucidation and identification of chemical substances. On the other hand, the enhanced predictive power of the combination of the two spectroscopic modes has until recently been hampered by the difficulty of obtaining satisfactory Raman spectra. The advent of laser technology has changed the situation and has brought Raman spectroscopy within the reach of every synthetic and analytical chemist. This book is the only collection of Raman and IR spectra plotted on the same wavenumber scale for a large number of carefully selected substances. 1044 organic compounds taken from all important classes of organic compounds have been measured under controlled experimental conditions. The spectra are arranged following a classification scheme especially developed for the atlas. An introductory text and several indexes to substance classes and names, molecular formulas, and CAS Registry Numbers add to the value of this unique tool. A first edition of this work was published as a loose-leaf collection in three volumes in the seventies and has long been sold out. The present revision is intended to meet renewed interest in Raman spectroscopy.
