El. knyga: VCD Spectroscopy for Organic Chemists

"The purpose of this book is to increase the awareness of organic chemists of the utility of VCD spectroscopy. To this end, successive chapters present experimental measurement of VCD spectra and their analysis; experimental measurement of vibrational absorption and VCD spectra; fundamental quantum-mechanical theory of the vibrational states of molecules and of their vibrational absorption and VCD spectra; application of the ab initio HF and DFT methods of quantum chemistry to the prediction of the molecular structures and vibrational states of organic molecules; conformational analysis of conformationally-flexible molecules; analysis of the vibrational absorption and VCD spectra of a number of conformationally-rigid chiral organic molecules; and studiesof a set of chiral organic molecules which further document the power of VCD spectroscopy and make clear how wide is the applicability of this technique"--

Stephens, Frank J. Devlin (both U. of Southern California), and James R. Cheeseman, with a Connecticut company, explain how vibrational circular dichroism (VCD) can be used to determine the chiral state of molecules, which is important to organic chemists and pharmaceutical chemists. They cover the experimental measurement of vibrational absorption and vibrational circular dichroism spectra, the theory of infrared and VCD spectra, ab initio methods, conformational analysis, analyzing the infrared and VCD spectra of conformally rigid molecules, and applying VCD spectroscopy to organic chemistry.

Stimulated by the increasing importance of chiral molecules as pharmaceuticals and the need for enantiomerically pure drugs, techniques in chiral chemistry have been expanded and refined, especially in the areas of chromatography, asymmetric synthesis, and spectroscopic methods for chiral molecule structural characterization. In addition to synthetic chiral molecules, naturally occurring molecules, which are invariably chiral and generally enantiomerically enriched, are of potential interest as leads for new drugs.

VCD Spectroscopy for Organic Chemists discusses the applications of vibrational circular dichroism (VCD) spectroscopy to the structural characterization of chiral organic molecules. The book provides all of the information about VCD spectroscopy that an organic chemist needs in order to make use of the technique. The authors, experts responsible for much of the existing literature in this field, discuss the experimental measurement of VCD and the theoretical prediction of VCD. In addition, they evaluate the advantages and limitations of the technique in determining molecular structure.

Given the availability of commercial VCD instrumentation and quantum chemistry software, it became possible in the late 1990s for chemists to use VCD in elucidating the stereochemistries of chiral organic molecules. This book helps organic chemists become more aware of the utility of VCD spectroscopy and provides them with sufficient knowledge to incorporate the technique into their own research.
