Stereodynamics Of Molecular Systems

Stereodynamics of Molecular Systems covers the proceedings of a symposium held at the State University of New York at Albany, on 23-24 April 1979. The book focuses on the stereodynamics of molecules and ions and nucleic acid structure. The contributions tackle spectroscopy, crystallography, perturbations, and electron-transfer reactions. The selection first offers information on nuclear magnetic resonance spectroscopy chemical shifts, coupling constants, and molecular geometry, including chemical shifts, bond coupling constants, and constitutional features of nucleic acids. The book then takes a look at nuclear magnetic resonance spectroscopy stereodynamics of small molecules; nuclear magnetic resonance spectroscopy solution dynamics of polymer chains; and single crystal crystallography. The publication evaluates the steric effects on electron-transfer reactions of sulfonamides; effects of isotopic perturbation on NMR spectra; and conformational mobility of the backbone of cyclic tripeptides. The book also discusses accessible surface areas of nucleic acids and their relation to folding, conformational transition, and protein recognition. Topics include polarity of exposed atoms, surface of DNA double helices, transfer RNA, and calculation of “static“ accessible surface area. The selection is a dependable reference for readers interested in the stereodynamics of molecules and ions and nucleic acid structure.

This volume contains a selection of scientific papers related to the structure and dynamics of non-rigid molecules. This frontline topic was born a few decades ago, when Longuet-Higgins proposed his famous theory of Molecular Symmetry Groups (Mol. Phys. 6, (1962) 457). Unfortunately, since this early paper, very few publications have been devoted to the study of non-rigid molecules. Let us mention some books which dedicate some chapters to them: Induced Representations in Crystals and Molecules, by S. L. Altmann, Academic Publishers, 1977; Molecular Symmetry and Spectroscopy, by P. R. Bunker, Academic Publishers, 1979; and finally Large Amplitude Motion in Molecules, Vols. I and II, by several authors, Springer Verlag, 1979. More recently an International Symposium on Non-Rigid Molecules was held in Paris, France, from 1-7 July 1982, the proceedings of which were published in the volume entitled Symmetries and Properties of Non-Rigid Molecules. A Comprehensive Survey, edited by J. Maruani et al., Elsevier, 1983. Finally, we should mention the very specialized work The Permutational Approach to Dynamic Stereochemistry, by J. Brocas et al., McGraw-Hill, 1983. The purpose of this book is to fill in this information on the structure and dynamics of non-rigid systems. To this aim, we have gathered a collection of recent papers written by the most qualified specialists in the world, covering a large field from van der Waals molecules to inorganic complexes and organic polyrotor molecules, as well as considering statistical and dynamic aspects.

The Fifteenth Jerusalem Symposium reflected the high standards of the former international scientific meetings, which convene once a year at the Israel Academy of Sciences and Humanities in Jerusalem to discuss a specific topic in the broad area of quantum chemistry and biochemistry. The topic at this year's Jerusalem Symposium was intramo lecular dynamics, a subject of central interest for theoreticians, che mists and biologists. During the last two decades, there has been remarkable pro gress in our understanding of time dependent phenomena. The development and application of the modern techniques of quantum mechanics and sta tistical mechanics to excited-state dynamics and to chemical and biophy sical systems constitutes a fast developing current research area. The main theme of the Symposium was built around a conceptual framework for the elucidation of photophysical and photochemical phenomena in atoms, molecules, van der Waals complexes and clusters, condensed phases, poly mers and biological supermolecules. The interdisciplinary nature of this research field was deliberated by intensive and extensive interactions between scientists from different disciplines and between theory and experiment. This volume provides a record of the invited lectures at the Symposium.

First multi-year cumulation covers six years: 1965-70.
