Book Synopsis Linear Dichroism and Circular Dichroism by : Bengt Nordén
Download or read book Linear Dichroism and Circular Dichroism written by Bengt Nordén and published by Royal Society of Chemistry. This book was released on 2019-05-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Studies on Polarised Light Spectroscopy by : Max Bergkvist
Download or read book Studies on Polarised Light Spectroscopy written by Max Bergkvist and published by Linköping University Electronic Press. This book was released on 2019-07-23 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. Three studies were done with human subjects and one with an animal model, to validate and compare the TiVi technique with laser Doppler flowmetry, which is an established method of measuring dermal microcirculation. The TiVi consists of a digital camera with polarisation filters in front of the flash and lens, with software for analysis of the picture. When taking a picture with the TiVi, the polarised light that is reflected on the skin surface is absorbed by the second filter over the lens (which is perpendicular to the first filter) but a portion of light penetrates the surface of the skin and is scattered when it is reflected on tissue components. This makes the light depolarised, passes the second filter, and produces a picture for analysis. The red blood cell (RBC) has a distinct absorption pattern that differs between red and green colour compared to melanin and other components of tissue. This difference is used by the software that calculates differences in each picture element and produces a measure of output which is proportional to the concentration of red blood cells. The oxygenation of RBC can also be calculated, as there is a difference in absorption depending on oxygen state. The first paper takes up possible sources of error such as ambient light, and the angle and distance of the camera. The main experiment was to investigate how the local heating reaction is detected with TiVi compared to LDF. In the second paper arterial and venous stasis are examined in healthy subjects with TiVi. The Third paper is an animal study where skin flaps were raised on pigs, and the vascular pedicle is isolated to enable control of inflow and outflow of blood.The measurements were made during partial venous, total venous, and total arterial occlusion. The TiVi recorded changes in the concentration of RBC, oxygenation and heterogeneity and the results were compared with those of laser Doppler flowmetry. In the fourth paper oxygenation and deoxygenation of RBC: s was studied. Studies were made on the forearms of healthy subjects who were exposed to arterial and venous occlusion. Simultaneous measurements were made with TiVi and Enhanced perfusion and oxygen saturation or EPOS, which is a new device that combines laser Doppler flowmetry and diffuse reflectance spectroscopy in one probe. With TiVi, one can measure RBC concentration and oxygenation in the area of an entire picture or in one or multiple user defined regions of interest (ROI). Methods such as laser Doppler flowmetry makes single point measurements, which is a potential source of error both because of the heterogeneity of the microcirculation, and that the circulation be insufficient in the margins of the investigated area. TiVi has been able to measure venous stasis more accurately than laser Doppler flowmetry, and venous stasis is the more common reason for flaps to fail. The TiVi is an accurate way to measure the concentration of RBC and trends in oxygenation of the dermal microcirculation. It has interesting possible applications for microvascular and dermatological research, monitoring of flaps, and diagnosis of peripheral vascular disease. Future clinical studies are needed as well as development of the user interface.

Download or read book Circular Dichroism and Linear Dichroism written by Alison Rodger and published by Oxford University Press, USA. This book was released on 1997 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Linearly Polarized IR Spectroscopy by : Bojidarka Ivanova
Download or read book Linearly Polarized IR Spectroscopy written by Bojidarka Ivanova and published by CRC Press. This book was released on 2024-11-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique that is useful in the study of pharmaceutical products and biological molecules, polarization IR spectroscopy has undergone continuous development since it first emerged almost 100 years ago. Capturing the state of the science as it exists today, Linearly Polarized IR Spectroscopy: Theory and Applications for Structural Analysis demonstrates how the technique can be properly utilized to obtain important information about the structure and spectral properties of oriented compounds. The book starts with the theoretical basis of linear-dichroic infrared (IR-LD) spectroscopy and then moves on to examine the background of the orientation method of colloid suspensions in a nematic host. It explores the orientation procedure itself, experimental design, and mathematical tools for the interpretation of the IR spectroscopic patterns. Next, the authors describe the structural elucidation of inorganic and organic compounds and glasses. Finally, they discuss applications in pharmaceutical analysis and the chemistry of dyes. Filled with more than 140 illustrations along with a color insert, the book explains both the scope of the polarized IR spectroscopy method as well as its limitations. A powerful source of information not only for specialists in IR spectroscopy, but also for those working in the field of structural analysis, this volume moves the field closer to developing an inherently classical method for the structural characterization of compounds.

Book Synopsis Raman/Infrared Atlas of Organic Compounds by : Bernhard Schrader
Download or read book Raman/Infrared Atlas of Organic Compounds written by Bernhard Schrader and published by Wiley-VCH. This book was released on 1996-12-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Polarized Light and the Mueller Matrix Approach by : Jose Jorge Gil Perez
Download or read book Polarized Light and the Mueller Matrix Approach written by Jose Jorge Gil Perez and published by CRC Press. This book was released on 2017-07-12 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Up-to-Date Compendium on the Physics and Mathematics of Polarization Phenomena Polarized Light and the Mueller Matrix Approach thoroughly and cohesively integrates basic concepts of polarization phenomena from the dual viewpoints of the states of polarization of electromagnetic waves and the transformations of these states by the action of material media. Through selected examples, it also illustrates actual and potential applications in materials science, biology, and optics technology. The book begins with the basic concepts related to two- and three-dimensional polarization states. It next describes the nondepolarizing linear transformations of the states of polarization through the Jones and Mueller–Jones approaches. The authors then discuss the forms and properties of the Jones and Mueller matrices associated with different types of nondepolarizing media, address the foundations of the Mueller matrix, and delve more deeply into the analysis of the physical parameters associated with Mueller matrices. The authors proceed to interpret arbitrary decomposition and other interesting parallel decompositions as well as compare the powerful serial decompositions of depolarizing Mueller matrix M. They also analyze the general formalism and specific algebraic quantities and notions related to the concept of differential Mueller matrix. The book concludes with useful approaches that provide a geometric point of view on the polarization effects exhibited by different types of media. Suitable for novices and more seasoned professionals, this book covers the main aspects of polarized radiation and polarization effects of material media. It expertly combines physical and mathematical concepts with important approaches for representing media through equivalent systems composed of simple components.
Book Synopsis Polarized Spectroscopy of Ordered Systems by : B. Samori'
Download or read book Polarized Spectroscopy of Ordered Systems written by B. Samori' and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
