Book Description
The mechanism of an elementary act is undoubtedly one of the most fundamental problems of chemical and, in particular, electro chemical kinetics. Although this problem has fascinated scientists for quite a long time, it was only in the late fifties and early sixties that it began to be actively investigated for charge transfer reactions. Owing to the development of new methods in the analysis of this problem, significant advancements were made in theoretical as well as experimental studies. These investigations showed that the physical mechanism of charge transfer in all processes including heterogeneous electrochemical and homogeneous chemical and bio chemical processes is basically the same. Hence, the results ob tained in the field of electrochemical kinetics are relevant to the understanding of homogeneous chemical reactions as well. This book endeavors to summarize the results of investigations carried out during the last two decades. It is based on the author's monograph "Electrode Reactions: The Mechanism of an Elementary Act" (Nauka, 1979). As compared to the first version, the book has been considerably revised and enlarged not only to include a large body of data published between 1978 and 1982, but also to analyze in detail the links between electrochemical and homogeneous, in particular enzymatic, kinetics. As a result, a new chapter has been added to the book. The change in the title reflects the fact that the material contained in the book is not restricted to an investigation of purely electrochemical problems.

Book Description
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.

Book Description
Electrochemical Kinetics: Theoretical Aspects focuses on the processes, methodologies, reactions, and transformations in electrochemical kinetics. The book first offers information on electrochemical thermodynamics and the theory of overvoltage. Topics include equilibrium potentials, concepts and definitions, electrical double layer and electrocapillarity, and charge-transfer, diffusion, and reaction overvoltage. Crystallization overvoltage, total overvoltage, and resistance polarization are also discussed. The text then examines the methods of determining electrochemical reaction mechanisms, including examination of the overall electrode reaction and determination of the type of overvoltage and reaction kinetics. A list of frequently used symbols is also provided. The book is a valuable reference for readers interested in the study of electrochemical kinetics.

Book Description
An elementary act of charge transfer determines a variety of phenomena in physics, chemistry and biology. The study of charge transfer processes has developed together with general progress in theoretical physics and in fast high resolution spectroscopy, so that research deals now with a broad class of systems, materials and environmental conditions. The specific topics covered are: (1) the environment and reactant-environment interaction at bulk and interfaces; (2) the elementary act of electron and proton transfer; homogeneous and heterogeneous processes; (3) processes of ion and heavy group transfer; ion transport in complex systems; (4) artificially and naturally organized charge transfer in physics, chemistry and biology, technological applications (molecular electronics, sensors, modified electrodes, membrane transport).

Book Description
The investigation of the elementary reactions of reactive intermediate species began about half a centruy ago with the advent of free radical kinetics as an active area of chemical research. In spite of the relatively greater ease of detection of a species carrying an electrical charge, and the fact that organic chemists had for decades postulated mechanisms involving ionic intermediates, the systematic study of the elementary reactions of ions was delayed for more than twenty years after the first beginnings of free radical kinetics. Even at this writing, in 1978, the word "kinetics" is considered by many chemists to be synomomous with "kinetics of neutral species". Yet in spite of the relatively late start and separation from the mainstream of kinetics, the field of ion physics and chemistry is fluorishing, and growing at an ever faster pace. Instrumentalists devise ever more sophisticated apparatuses with capabilities of delving into nearly every aspect of the interactions between ions and molecules. Even satellites orbiting the earth are now being used effectively to determine rate coefficients of ionospheric ion-neutral reactions, some of which can not as yet be measured in the laboratory.

Book Description
Progress in Reaction Kinetics, Volume 9 summarizes recent advances that have been made with regards to reaction kinetics. Kinetic applications of nuclear magnetic resonance spectroscopy are described, and tunneling reactions of solvated electrons in liquids and glasses are discussed. The reactions of free radicals generated by organic compounds are also considered. This volume consists of three chapters and begins with a discussion of basic NMR theory, including the NMR phenomenon and nuclear spin relaxation processes. Special attention is paid to the dynamic characteristics of chemical exchange reactions which occur in a system at equilibrium, along with techniques for determining chemical exchange parameters from time domain spectra and time dependent frequency domain spectra. The reader is then introduced to tunneling reactions of solvated electrons in liquids and glasses, with emphasis on the mode of transport by which the electron induces such a reaction. A model of diffusion-controlled reactions incorporating a tunneling reaction mechanism is described. A chapter analyzing the use of radiation to produce reactions of free radicals from organic compounds in aqueous solution, including hydrocarbons and carbonyl compounds, concludes the book. This book will be of interest to scientists, students, and researchers working in the fields of chemistry and the molecular sciences.

Book Description
Volumes 26 and 27 are both concerned with reactions occurring at electrodes arising through the passage of current. They provide a comprehensive review of the study of electrode kinetics. The basic ideas and experimental methodology are presented in Volume 26 whilst Volume 27 deals with reactions at particular types of electrodes.Chapter 1 serves as an introduction to both volumes and is a survey of the fundamental principles of electrode kinetics. Chapter 2 deals with mass transport - how material gets to and from an electrode. Chapter 3 provides a review of linear sweep and cyclic voltammetry which constitutes an extensively used experimental technique in the field. Chapter 4 discusses a.c. and pulse methods which are a rich source of electrochemical information. Finally, chapter 5 discusses the use of electrodes in which there is forced convection, the so-called ``hydrodynamic electrodes''.
