Linear Dichroism and Circular Dichroism by Bengt Nordén,Alison Rodger,Tim Dafforn Pdf

This book provides an introduction to optical anisotropy (linear dichroism, LD) and optical activity (circular dichroism, CD) as techniques for the study of structures and interactions of molecules in solution. The book covers the use of these techniques for both small and large molecular systems with particular emphasis being placed on proteins and nucleic acids. CD is a well-established technique and this book aims to explain how it can be used simply and effectively for new entrants to the field as well as covering more advanced techniques for experts. LD is often seen as a rather exotic method intended only for experienced spectroscopists. This book demonstrates that it is an approach with real utility that may be used by both students and scientists from graduate level onwards to give simple answers, which are not available from any other technique, to structural and kinetic questions. Much of the emphasis is on flow orientation of samples in solution phase. The book first describes the techniques and the information they can provide; it then goes on to give specific details on how to actually implement them, including a wide range of examples showing how LD and CD can help with * protein and nucleic acid secondary structure elucidation; * analysis of the formation and rearrangements of fibrous proteins and membrane proteins; * identification of the absolute configuration of small molecules; * determination of the orientation of small molecules in anisotropic media; * assignment of transition moment polarizations; * investigation of binding strengths and geometries of ligand-macromolecule complexes; * 3-D structure determination from LD, molecular replacement and MD modeling. The advantages of combined LD/CD studies are also outlined with examples of DNA/drug complexes and protein insertion into membranes. Taken together the book represents a comprehensive text on the theory and application of LD and CD in the chemical and biological sciences.

Circular Dichroism and Linear Dichroism by Alison Rodger,Bengt Nordén Pdf

This book provides an introduction to all those who wish to use the complementary spectroscopic techniques of optical activity (circular dichroism, CD) and optical anisotropy (linear dichroism, LD) for the study of the structure of molecules and interactions between molecules in solution. It emphasizes these techniques and how to use them for both low and high molecular weight molecules. The book begins by describing the principles behind CD and LD and how these techniques can be used in the laboratory without using advanced maths or quantum mechanics. The next chapters describe how both techniques may be applied to the study of biological macromolecules and give a detailed description of how they may be used on small molecules to investigate molecular and electronic structure. The final part contains theoretical derivations of all the equations required for the applications described previously. Specific molecular examples are used to illustrate concepts and to show the reader how to use the techniques in chemical and biological systems. Circular Dichroism and Linear Dichroism is an easy guide to what a prospective user of CD needs to know and explains how LD is not merely an exotic technique only to be practiced by experienced spectroscopists, but may be routinely and usefully employed as an aid to molecular structure determination.

Polarized Spectroscopy of Ordered Systems by B. Samori',E.W. Thulstrup Pdf

Ordered systems exhibit physical properties and behavior unknown in media where structural ordering and organization do not take place. In ordered systems special correlations between molecules exist and the results are remarkable properties: the functional order of biological systems, the electrooptical and mechanical proper ties of liquid crystalline materials and stretched polymers are just a few examples. New methods and techniques in optical spectroscopy have recently been developed to study ordered systems and guest molecules. This stimulated the organization of a NATO Advanced Study Institute bringing together chemists and physicists from optical spectroscopy, materials science, and biology. Thereby a unifying and interdisciplinary survey of possible applications of spectroscopy with polarized light to ordered systems, such as liquid crystals, stretched polymers, polymeric liquid crystals, and membranes, was achieved. The interdisciplinary approach of the meeting is reflected in the book. Different aspects of the same topic are often treated in several chapters all through the book. Therefore, each reader should look for the contributions which serves his needs, even if this means that some chapters will be skipped. The Advanced Study Institute, "New Developments in Polarized Spectroscopy of Ordered Systems", was the first scientific event of the celebrations of the 900th anniversary of the University of Bologna. The international and multidisciplinary approach of this ASI well converged in the tradition of the "Studium" at Bologna.

Circular Dichroism and Magnetic Circular Dichroism Spectroscopy for Organic Chemists by Nagao Kobayashi,Atsuya Muranaka Pdf

CD and MCD spectroscopy can provide key information about the conformations and electronic states of chromophore containing molecules. However, the theory has remained too challenging and inaccessible for many organic chemists and biochemists and only a few researchers have carried out detailed quantitative analyses of their spectral data. This is not surprising as people who excel at spectroscopic theory usually lack the skills set required to design and synthesise the molecules that would be most appropriate for describing and explaining the theory of CD and MCD spectroscopy. Most of the books that have been written on the subject have, therefore, been based on very dense sets of mathematical equations. This timely book rectifies that situation by summarizing the relationship between the different types of spectra and by describing in detail the qualitative and quantitative methods which can readily be used to analyse CD and MCD spectral data. During the last decade the authors have successfully synthesized several molecules to illustrate key points related to the theory of CD and MCD spectroscopy, resulting in this definitive book providing key practical knowledge in a readily accessible style. It is aimed primarily at organic chemists and biochemists and is required reading for researchers active in the field. In the introduction, the book describes the types of information that can be derived from CD and MCD spectroscopy. After a detailed explanation of the theory of electronic absorption spectroscopy, it then provides practical in depth examples of the various analytical methods that can be carried out with CD and MCD spectral data. This makes the theory of these techniques much more accessible for researchers who do not specialise in physical chemistry. The book concludes by briefly summarizing the key mathematical expressions associated with each technique.
