Download or read book Charge Transfer Processes in Condensed Media written by J. Ulstrup and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecules in liquid and solid media are exposed to strong inter action forces from the surrounding medium. The formulation of a comprehensive theory of chemical processes in condensed media is consequently an elaborate task involving concepts from several areas of the natural sciences. Within the las~ two and a half decades very notable results towards the formulation of a 'unified' quantum mechanical theory of such processes have in fact been achieved, and by the variety of physical, chemical, and biological processes which can be suitably covered by this framework, the new theory represents an adequate alternative to the transition state theory. The present work has a two-fold purpose. Firstly, to provide a reasonably organized exposition of some basic aspects of these developments. This part emphasizes the fundamental similarities between chemical and other kinds of radiationless processes and includes the derivation of the most important rate expressions without resorting to involved mathematical techniques. The s- ond major purpose is to illustrate the 'unified' character of the rate theory by analysis of a considerable amount of expe- mental data from both 'conventional' kinetics and from such untraditional areas as low-temperature, strongly exothermic, and biological processes. Particular attention is here given to those systems for which a classical description is inadequate, and which provide a diagnostic distinction between several alternative theoretical approaches.

Available in PDF, EPUB and Kindle. Book excerpt: This unified approach to charge transfer science provides a valuable tool for the increasing number of theoretical and experimental scientists involved in such areas as physical chemistry, electrochemistry, chemical physics, biophysics, biochemistry, and solid-state and surface physics. This comprehensive monograph presents the process of charge transfer in the traditionally independent fields of physics, chemistry and biology from a unified point of view. The numerous facets of charge transfer are presented coherently, emphasising the common nature of phenomena which at first sight appear quite different. Detailed theoretical overviews are presented and phenomena such as redox, electrochemical and radiative processes, polarons, proton transfer and biological processes are discussed. All major results of the different processes in physics, chemistry and biology are discussed in detail with special reference to their physical mechanisms, thereby allowing a unified conceptual approach to be applied

Book excerpt: Charge and Energy Transfer Dynamics in Molecular Systems Comprehensive resource offering knowledge on charge and energy transfer dynamics in molecular systems and nanostructures Charge and Energy Transfer Dynamics in Molecular Systems provides a unified description of different charge and energy transfer phenomena in molecular systems with emphasis on the theory, bridging the regimes of coherent and dissipative dynamics and thus presenting classic rate theories as well as modern treatments of ultrafast phenomena. Starting from microscopic models, the common features of the different transfer processes are highlighted, along with applications ranging from vibrational energy flow in large polyatomic molecules, the motion of protons in solution, up to the concerted dynamics of electronic and nuclear degrees of freedom in molecules and molecular aggregates. The newly revised and updated Fourth Edition contains a more detailed coverage of recent developments in density matrix theory, mixed quantum-classical methods for dynamics simulations, and a substantially expanded treatment of time-resolved spectroscopy. The book is written in an easy-to-follow style, including detailed mathematical derivations, thus making even complex concepts understandable and applicable.

Download or read book Molecular Associations in Biology written by Bernard Pullman and published by Elsevier. This book was released on 2012-12-02 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Associations in Biology provides information pertinent to molecular biology. This book discusses several topics, including DNA replication, calculation of intermolecular energies, and thermodynamic parameters of polynucleotides. Organized into 35 chapters, this book starts with an overview of the specific association of the purine and pyrimidine bases in the nucleic acids, which provides the basis for storage, expression, and transmission of genetic information. This text then explores the secondary structures, interactions, and replication processes of nucleic acids. Other chapters consider the complex biological process of protein synthesis. This book discusses as well the methods of photodynamic action, which is significant in detecting energy transfer from dye to the biomolecule and identifying the free radicals produced. The final chapter deals with the macroscopic properties of molecular systems, which refer to such concepts as volume, mass, pressure, temperature, and pH. This book is a valuable resource for biophysicists, organic chemists, biochemists, and biologists.

Download or read book Modern Bioelectrochemistry written by F. Gutmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: As stated by Buckminster Fuller in Operation Manual for Spaceship Earth, "Synergy is the behavior of whole systems unpredicted by separately observed behaviors of any of the system's separate parts". In a similar vein, one might define an intellectual synergy as "an improvement in our understanding of the behavior of a system unpredicted by separately acquired viewpoints of the activities of such a system". Such considerations underlie, and provide a motivation for, an interdisciplinary approach to the problem of unraveling the deeper mysteries of cellular metabolism and organization, and have led a number of pioneering spirits, many represen ted in the pages which follow, to consider biological systems from an elec trochemical standpoint. is itself, of course, an interdisciplinary branch of Now electrochemistry science, and there is no doubt that many were introduced to it via Bockris and Reddy's outstanding, wide-ranging and celebrated textbook Modern Electrochemistry. If I am to stick my neck out, and seek to define bioelec trochemistry, I would take it to refer to "the study of the mutual interac tions of electrical fields and biological materials, including living systems".
