Book Description
For Louis Pasteur, the two distinctive properties of dissymmetric systems, optical activity and chiral discrimination, provided prime evidence for a Divine origin to the universe. Handedness appeared to be built into the macrocosm of the galaxies, each with a non-superposable mirror image by virtue of its rotation, as well as the microcosm of each molecule of most natural products. The best that the chemist in the laboratory could accomplish appeared to be the synthesis of the detordu internally-compensated meso-form and, as Pasteur ultimately came to admit, the externally-compensated racemic form. In the latter case the chemist generated not merely one but two chiral structures, although parity, and secondary symmetry generally, seemed to be conserved in the enantiomer antipode pair. The cosmic element in the Pasteur tradition received an augmentation in secular form from demonstrations of the non conservation of parity in the weak interactions, and from the discovery of net circularity in the extra-terrestrial photons, such as those from the less-distant planets, particularly the photons from the Jupiter red-spot. The development of the photoacoustic circular analysers a decade ago was received in fact with as much enthusiasm by the astronomers as by the chemists. It would be just to add, however, that the majority of these circular analysers are now to be found, not in the observatories, but in the physical and chemistry laboratories devoted to the molecular aspects of the Pasteur tradition.

Book Description
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 Description
As the need for accurate and non-invasive optical characterization and diagnostic techniques is rapidly increasing, it is imperative to find improved ways of extracting the additional information contained within the measured parameters of the scattered light. This is the first specialized monograph on photopolarimetry, a rapidly developing, multidisciplinary topic with numerous military, ecological remote-sensing, astrophysical, biomedical, and technological applications. The main objective is to describe and discuss techniques developed in various disciplines to acquire useful information from the polarization signal of scattered electromagnetic waves. It focuses on the state-of-the-art in polarimetric detection, characterization, and remote sensing, including military and environmental monitoring as well as terrestrial, atmospheric, and biomedical characterization. The book identifies polarimetric techniques that have been especially successful for various applications as well as the future needs of the various research communities. The monograph is intended to facilitate cross-pollination of ideas and thereby improve research efficiency and help advance the field of polarimetry into the future. The book is thoroughly interdisciplinary and contains only invited review chapters written by leading experts in the respective fields. It will be useful to science professionals, engineers, and graduate students working in a broad range of disciplines: optics, electromagnetics, atmospheric radiation and remote sensing, radar meteorology, oceanography, climate research, astrophysics, optical engineering and technology, particle characterization, and biomedical optics.

Book Description
An overview of the importance and consequences of asymmetry from molecules to the macroscopic world As scientists have become more capable of probing the structure of three-dimensional objects at the molecular level, the need to understand the concept and the consequences of mirror-image asymmetry—chirality—has increased enormously. Written at an introductory level, Mirror-Image Asymmetry provides an overview of the importance and effects of asymmetry from the atomic and molecular world of physics and chemistry to the organisms and structures that we see and use in our everyday life. The reader will develop a broad appreciation of three-dimensional asymmetry from the microscopic molecular world to the macroscopic world of handedness, automobile driving, windmills, sports, and similar phenomena. The book features: An introduction to basic definitions and the nomenclature of asymmetric and dissymmetric molecules Up-to-date examples of the importance and consequences of asymmetry in modern drug applications, current theories of the origin of asymmetry in nature, and examples of molecular asymmetry in smell, taste, and insect communication Many illustrations, chemical structures, and photographs that enable the reader to connect the actual asymmetrical structures to the different phenomena that depend on structural asymmetry In the 150 years since Louis Pasteur discovered asymmetry in molecular structures, scientists have made great progress in understanding how interactions between chiral molecules influence biochemical processes. This knowledge is leading to very sophisticated asymmetric synthetic techniques that have greatly benefitted many research groups especially those in the pharmaceutical industry. This guide to the role of molecular and macroscopic chirality will inspire students and scientists in chemistry, biology, physics, and drug discovery.
