The transition state is the critical configuration of a reaction system situated at the highest point of the most favorable reaction path on the potential-energy surface, its characteristics governing the dynamic behavior of reacting systems decisively. This text presents an accurate survey of current theoretical investigations of chemical reactions, with a focus on the nature of the transition state. Its scope ranges from general basic theories associated with the transition states, to their computer-assisted applications, through to a number of reactions in a state-of-the-art fashion. It covers various types of gas-phase elementary reactions, as well as some specific types of chemical processes taking place in the liquid phase. Also investigated is the recently developing transition state spectroscopy. This text will not only serve as a contemporary reference book on the concept of the transition state, but will also assist the readers in gaining valuable key principles regarding the essence of chemical kinetics and dynamics.

The transItIOn-state theory has been, from the point of its inception, the most influential principle in the development of our knowledge of reaction mechanisms in solution. It is natural that as the field of biochemical dynamics has achieved new levels of refinement its students have increasingly adopted the concepts and methods of transition-state theory. Indeed, every dynamical problem of biochemistry finds its most elegant and economical statement in the terms of this theory. Enzyme catalytic power, for example, derives from the interaction of enzyme and substrate structures in the transition state, so that an understanding of this power must grow from a knowledge of these structures and interactions. Similarly, transition-state interactions, and the way in which they change as protein structure is altered, constitute the pivotal feature upon which molecular evolution must turn. The complete, coupled dynamical system of the organism, incorporating the transport of matter and energy as well as local chemical processes, will eventually have to yield to a description of its component transition-state structures and their energetic response characteristics, even if the form of the description goes beyond present-day transition-state theory. Finally, the importance of biochemical effectors in medicine and agriculture carries the subject into the world of practical affairs, in the use of transition-state information for the construction of ultra potent biological agents.

Reaction Rate Theory and Rare Events bridges the historical gap between these subjects because the increasingly multidisciplinary nature of scientific research often requires an understanding of both reaction rate theory and the theory of other rare events. The book discusses collision theory, transition state theory, RRKM theory, catalysis, diffusion limited kinetics, mean first passage times, Kramers theory, Grote-Hynes theory, transition path theory, non-adiabatic reactions, electron transfer, and topics from reaction network analysis. It is an essential reference for students, professors and scientists who use reaction rate theory or the theory of rare events. In addition, the book discusses transition state search algorithms, tunneling corrections, transmission coefficients, microkinetic models, kinetic Monte Carlo, transition path sampling, and importance sampling methods. The unified treatment in this book explains why chemical reactions and other rare events, while having many common theoretical foundations, often require very different computational modeling strategies. Offers an integrated approach to all simulation theories and reaction network analysis, a unique approach not found elsewhere Gives algorithms in pseudocode for using molecular simulation and computational chemistry methods in studies of rare events Uses graphics and explicit examples to explain concepts Includes problem sets developed and tested in a course range from pen-and-paper theoretical problems, to computational exercises

This book furthers readers’ understanding of the amazing features of six-membered transition states in stereoselective organic reactions. Comprehensive and logically organized, it covers reactions classified in four categories: [3,3]-sigmatropic rearrangements, aldol reactions, metal allylation reactions, and stereoselective reductions. There is a thorough discussion of each reaction category, along with computational studies that support a proposal of a six-membered state. The book assists professors, researchers, and students in proposing reasonable transition states for the description of newly discovered stereoselective reactions.

This volume addresses fundamental questions concerning the immunological genesis of the catalytic activity in antibodies, its relationship with classical antigen binding activity, and the biochemical mechanisms involved in catalysis. The contents reflect three main challenges in the field, i.e. to delineate the biological functions of catalytic antibodies in autoimmune disease; to isolate therapy-grade antibody catalysts with sufficient specificity and turnover to permit rapid removal of microbial and tumor antigens; and to develop immunogens that recruit immature catalyst-producing B cells into the clonal selection pathway and induce adaptive improvements of the catalytic function. Well-edited and up-to-date, this book reviews the current knowledge in the field and explores ways by which natural and engineered catalytic activities can be harnessed for medical applications. It should therefore be of special interest to immunologists, biochemists, biotechnologists, rheumatologists and pathologists.
