Book Synopsis Spectroscopy and Photochemistry of Uranyl Compounds by : Eugene Rabinowitch
Download or read book Spectroscopy and Photochemistry of Uranyl Compounds written by Eugene Rabinowitch and published by Elsevier. This book was released on 2013-10-22 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy and Photochemistry of Uranyl Compounds is a guide to the research and physics of the actinide elements, particularly the uranyl ion. The book is introduced with the subject of the spectroscopy of uranyl salts in the solid state. Studies dealing with the fluorescence and absorption spectra of solid uranyl salts through band measurements and empirical classification, term analysis, and fluorescence spectrum in relation to excitation by light of various wavelengths are then discussed. The book also mentions the analysis of the uranyl spectrum by Dieke and co-workers, because of the precise measurements of the fluorescence and absorption bands obtained under the Manhattan project. The table determined by Pant and Sakhwalkar in their study of the florescence spectrum of solid, hydrated uranyl fluoride at -185 degrees centigrade is presented. The text also discusses the theory of electronic structure and spectra of the uranyl ion. The spectroscopy of uranyl compounds in solution and the uranyl fluorescence intensity and decay are then presented. The book then explains the process of measuring the intensity of slowly decaying florescence of uranyl salts. The primary photochemical reactions in uranyl compounds are found to be slow, giving rise to many secondary thermal reactions that may be unwanted. Researchers in the fields of chemistry and physics working on actinide elements will find this collection of monographs invaluable.

Download or read book Zero-Phonon Lines written by Olev Sild and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers are playing a more and more dominant role in modern optical spec troscopy, offering an increased potential for high resolution and, thus, for more detailed spectroscopic information on dynamic and structural param eters. This book on Zero-Phonon Lines and Spectral Hole Burning in Spec troscopy and Photochemistry gives a concise and very useful survey of some of the pioneering and current work on solid state spectroscopy of various groups in the USSR. It focusses on the optical Mossbauer analogue, the "zero-phonon line", and "hole burning" spectroscopy, a method which increases the resolu tion well beyond the zero-phonon linewidth. In this conte. . 'Ct, the present work is complementary to Persistent Spectral Hole-Burning: Science and Applica tions (ed. by W.E. Moerner, Springer, Berlin, Heidelberg 1988), which deals in more detail with the various aspects of laser spectroscopy with ultrahigh spectral resolution. Zero-phonon lines and an understanding of the various phonon coupling mechanisms which are treated in this book are a prerequi site for applying and understanding techniques of ultrahigh resolution such as hole-burning or optical echoes. Bayreuth, March 1988 D. Haarer Preface The investigation of zero-phonon lines (ZPLs) is one of the foremost and most informative fields of present-day condensed-matter spectroscopy. Along with its definite function in physical cognition and investigation methods, the spectroscopy of ZPLs is also gaining purely practical applications. This is due to the fact that ZPLs are extra-sensitive quantum-mechanical detectors.

Download or read book Photochemistry written by Oliver Schalk and published by American Chemical Society. This book was released on 2021-03-30 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochemistry is an important part of both chemistry and biology and is of great practical significance for the development of sustainable sources of energy. The mechanisms of photochemistry are far from trivial and far from understood. There are limits to how well theory can describe the processes and how well experiments can resolve them. This book aims to provide an overview of state-of-the-art methods for both theoretical development and experimental techniques, with a focus on ultrafast molecular processes and electronic excitation of organic molecules. These fields are active and progress is being made, carried by the increasing speed of computation and the development of new light sources, most notably X-ray sources at large facilities. Alongside these two layers of theoretical development and experimental techniques is a third layer—model building. In this layer, model building tries to find similarities in seemingly unrelated experimental results and deepen our general knowledge of photoinduced processes. Often, progress is made not by cutting-edge techniques but rather by using well-established techniques with a great variety of molecules—this approach promises less glory but is just as important as the first two layers. Examples mentioned in the text are the Woodward–Hoffman rules and the dynamophore concept. All three layers are crucial to push our knowledge further and, eventually, to use it for developing new and more advanced optical devices.

Book Synopsis Applied Photochemistry by : Rachel C. Evans
Download or read book Applied Photochemistry written by Rachel C. Evans and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Photochemistry encompasses the major applications of the chemical effects resulting from light absorption by atoms and molecules in chemistry, physics, medicine and engineering, and contains contributions from specialists in these key areas. Particular emphasis is placed both on how photochemistry contributes to these disciplines and on what the current developments are. The book starts with a general description of the interaction between light and matter, which provides the general background to photochemistry for non-specialists. The following chapters develop the general synthetic and mechanistic aspects of photochemistry as applied to both organic and inorganic materials, together with types of materials which are useful as light absorbers, emitters, sensitisers, etc. for a wide variety of applications. A detailed discussion is presented on the photochemical processes occurring in the Earth’s atmosphere, including discussion of important current aspects such as ozone depletion. Two important distinct, but interconnected, applications of photochemistry are in photocatalytic treatment of wastes and in solar energy conversion. Semiconductor photochemistry plays an important role in these and is discussed with reference to both of these areas. Free radicals and reactive oxygen species are of major importance in many chemical, biological and medical applications of photochemistry, and are discussed in depth. The following chapters discuss the relevance of using light in medicine, both with various types of phototherapy and in medical diagnostics. The development of optical sensors and probes is closely related to diagnostics, but is also relevant to many other applications, and is discussed separately. Important aspects of applied photochemistry in electronics and imaging, through processes such as photolithography, are discussed and it is shown how this is allowing the increasing miniaturisation of semiconductor devices for a wide variety of electronics applications and the development of nanometer scale devices. The final two chapters provide the basic ideas necessary to set up a photochemical laboratory and to characterise excited states. This book is aimed at those in science, engineering and medicine who are interested in applying photochemistry in a broad spectrum of areas. Each chapter has the basic theories and methods for its particular applications and directs the reader to the current, important literature in the field, making Applied Photochemistry suitable for both the novice and the experienced photochemist.

"A certain amount of energy destroys the same amount of CO2 according to the whether it is administered continuously or intermittently. In order to rationalize this result there are two possibilities, either the destruction of CO2 further occurred in the dark periods, which would lead to the same form of energy storing form, or in the illuminated period the reaction goes at twice the rate." O. Warburg, Biochem. Z., 1919, 100, 230-270.
