Molecular Structure, Symmetry, And Spectroscopy.pdf
Written in a clear and understandable manner, this book provides a comprehensive, yet non-mathematical, treatment of the topic, covering the basic principles of symmetry and the important spectroscopic techniques used to probe molecular structure. The chapters are extensively illustrated and deal with such topics as symmetry elements, operations and descriptors, symmetry guidelines, high-fidelity pseudosymmetry, crystallographic symmetry, molecular gears, and experimental techniques, including X-ray crystallography and NMR spectroscopy. As an additional feature, 3D animations of most of the structures and molecules covered are available online at wiley.com. As a result, chemists learn how to understand and predict molecular structures and reactivity. Authored by a renowned expert with numerous publications and an excellent track record in research and teaching, this is a useful source for graduate students and researchers working in the field of organic synthesis, physical chemistry, biochemistry, and crystallography, while equally serving as supplementary reading for courses on stereochemistry, organic synthesis, or crystallography.
Robert Glaser is Emeritus Professor of Chemistry at Ben-Gurion University of the Negev, Beer-Sheva, Israel. He also holds an appointment as Visiting Professor in the Cross-Border Program in Biological Chemistry Budejoice (Budaweis), Czech Republic, administered by the University of South Bohemia/Universitat Johannes Kepler in Linz, Austria. He also teaches at the Feinberg Graduate School of the Weizmann Institute of Science in Rehovot, Israel. Robert Glaser received his BA in chemistry at the University of Pennsylvania (USA) in 1963. Upon graduation he worked as a development chemist in the Structural Adhesives Division of the Pittsburg Plate Glass Company. Concurrently, he undertook part-time MSc studies in polymer chemistry at the Polytechnic Institute of Brooklyn, USA. After three years he began full-time studies, graduating Rutgers State University, USA, in 1969. From 1969 - 1971 he spent a two-year postdoctoral fellowship at Princeton University (USA) under guidance of Prof. P. von Rague Schleyer and Prof. R. Landgridge. After immigrating to Israel in 1971, he built up a new Department of Chemistry at the recently established University of the Negev in Beer-Sheva, where he became full professor in 1997. He has authored over 100 publications on the topic of organic and inorganic stereochemistry, molecular modeling, computer assisted drug design, and structure determination via NMR spectroscopic techniques.
