Download or read book Surface Electron Transfer Processes written by R. J. Dwayne Miller and published by Wiley-VCH. This book was released on 1995-05-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an extensive theoretical treatment of surface electron transfer processes. The emphasis is on electronic coupling of molecular potentials to conducting band states. The essential role of surface electron transfer in catalysis, electrochemistry, photo imaging, and virtually all charge transfer solid state devices make this process one of the most important single chemical events. The assumptions in the theories will be highlighted and major emphasis will be placed on the unknown nature of the electronic coupling. This latter point is the driving force for current experiments in the area. The chapter on theory will form the cornerstone for the chapters covering experimental findings on surface processes. The book will be written in a fashion so as to be useful as a text book, yet emphasize the challenges that remain ahead in understanding electron tunneling phenomena. The book is written in a tutorial fashion at a level suitable for graduate students with little background in the area.

Download or read book Heterogenous Photochemical Electron Transfer written by Michael Gratzel and published by CRC Press. This book was released on 2018-01-18 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph attempts to unify these diverse and exciting new developments within a common framework. First, the physical principles underlying heterogenous electron-transfer processes are outlined in a concise way and are compared to the homogeneous counterpart. This analysis includes the notion of the Fermi level in liquids and solids as well as the distribution of electronic energy levels in solids and liquids. A comparison is made between the salient kinetic features of homogeneous and heterogeneous electron transfer reactions. This establishes the basis for the subsequent treatment of the transduction of excitation energy and photo-initiated electron transfer in organized molecular assemblies, such as micelles, vesicles and monolayers. Transmembrane redox processes are critically reviewed. Particular attention is given to semiconductor electrodes and particles. This includes a discussion of quantum size effects, the nature of space charge layers as well as surface states and the dynamics of charge carrier-induced redox reactions at the semiconductor solution interface. These processes are of fundamental importance in such diverse fields as photochromism, electrochromic displays, electroreprography and photography, information storage, photocatalysis, photodegradation of paints, and solar energy conversion.

This book was released on 2001-05-02 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron transfer is the most important process to take place in natural and artificial chemical systems, playing a fundamental role, for example, in photosynthesis as well as in photography. Electron transfer reactions - oxidations and reductions - are involved in, among others, a variety of energy conversion processes, analytical methods, synthetic strategies, and information processing systems. This five-volume work is the only comprehensive yet up-to-date reference on electron transfer processes. Following a foreword by Nobel prize-winner R. A. Marcus, renowned experts from all over the world provide an interdisciplinary overview of every aspect of electron transfer including theoretical-physicochemical backgrounds, latest analytical techniques to identify, monitor and measure the rate of electron transfer, utilizing electron transfer reactions in organic synthesis and catalysis, electron transfer in the gas phase or in special heterogeneous systems such as zeolites or sensitized electrodes. Other central issues are the study of biological systems and the biomimetic electron transfer processes in artificial supramolecular systems. Finally, a complete volume is dedicated to the application of electron transfer in molecular-level electronics, imaging processes and energy conversion. Each chapter is complemented by numerous tables, formulae and illustrations providing an indispensable wealth of information. All references are cross-indexed throughout the work for easy access to this highly complex topic. Whether for quickly looking-up a keyword or as a thorough introduction to a special aspect, this is an essential handbook for everyone working in the field, from experts to postgraduates, from synthetic chemists, physicochemists or biochemists to research groups in material sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Electron Transfer Chemistry, Volume 4 presents the reaction mechanisms involving the movement of single electrons. This book discusses the electron transfer reactions in organic, biochemical, organometallic, and excited state systems. Organized into four chapters, this volume begins with an overview of the photochemical behavior of two classes of sulfonium salt derivatives. This text then examines the parameters that control the efficiencies for radical ion pair formation. Other chapters consider the progress in the development of parameters that control the dynamics and reaction pathways for radical ion pairs produced by the diffusional quenching of photoexcited molecules. This book discusses as well the criteria for distinguishing concerted from stepwise mechanisms in electrochemical and homogeneous reductive cleavage reactions in polar solvents. The final chapter deals with excited-state chemical transformation, particularly on photoinduced SET reactions in which amines and related substances serve as electron donors. This book is a valuable resource for scientists and electrochemists.

This book was released on 2012-12-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living things use solar energy in two ways: in the transmission of information and in the conversion of light energy to chemical energy. In order to elucidate the molecular mechanisms of highly sensitive visual responses and other photosensitive responses of biological systems, and the very efficient transduction of photoenergy to chemical energy in photosynthesis, it is important to observe molecular processes in biological systems. Using highly developed laser spectroscopic techniques, great progress has recently been achieved in the area of various primary processes in photobiology. It was therefore an excellent time to hold the 12th Taniguchi International Symposium, Biophysics Division, on Primary Processes in Photobiology. This volume is the proceedings of that symposium. Among the topics discussed are the femtosecond molecular processes in photosynthetic bacteriochlorophyll and the recently discovered intermediates in the photocycles of rhodopsin (found in the visual pigments of many animals), bacteriorhodopsin (found in the proton-pumping pigments of halobacteria) and retinochrome. New techniques for the measurement of the primary processes are also reported.

Available in PDF, EPUB and Kindle. Book excerpt: Electron Transfer in Chemistry and Biology An Introduction to the Theory Alexander M. Kuznetsov Russian Academy of Sciences, Moscow, Russia Jens Ulstrup Technical University of Denmark, Lyngby, Denmark Electron transfer is perhaps the single most important physical event in chemical, electrochemical, photochemical, biochemical, and biophysical processes. The focus and ubiquity of electron transfer is intriguing and exciting but a coherent and comprehensive approach to this topic is at the same time a challenge. Electron Transfer in Chemistry and Biology provides a thorough and didactic approach to the theoretical basis of electron transfer phenomena. Not only does it offer a full introduction to this area and a discussion of its historical development, it also gives detailed explanations of difficult issues, for example, long-range electron transfers, stochastic and dynamic processes, and biological features. A wide variety of readers will find this volume of great interest, ranging from final year undergraduate students, postgraduate students and university lecturers, to research staff in numerous fields including medical companies, electronics industry, catalysis research and development, chemical industry and some hospitals.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of organic materials for solar energy conversion stands to benefit greatly from accurate, computationally tractable electronic structure methods for excited states. Here we apply two approaches based on density functional theory (DFT) to predict excitation energies and electron transfer parameters in organic chromophores and semiconductors in solution. First, we apply constrained DFT to characterize charge recombination in a photoexcited donor-acceptor dyad and to understand the photophysical behavior of a fluorescent sensor for aqueous zinc. Second, we discover that the delta-self-consistent-field ([Delta]SCF) approach to excited states in DFT offers accuracy comparable to that of the better-established but more indirect linear-response time-dependent DFT approach, and we offer some justification for the similarity. Finally, we investigate a spin-restricted analog of [Delta]SCF known as restricted open-shell Kohn-Sham (ROKS) theory. We resolve a known ambiguity in the formal solution of the ROKS equations for the singlet excited state by presenting a self-consistent implementation of ROKS with respect to the mixing angle between the two open shells. The excited state methods developed and applied in this work contribute to the expanding toolkit of electronic structure theory for challenging problems in the characterization and design of organic materials.
