Book Description
The chapters in this book are devoted to the elementary reactions of small molecules in the gas phase, with some emphasis on reactions important in combustion. The first three chapters cover experimental measurements made at high temperatures, mainly using shock waves and flames; the final chapter describes discharge flow methods near room temperature. The authors-all active in the fields they describe were asked to aim at a level intermediate between a textbook and a review, designed for readers not already familiar with this branch of chemical kinetics. We hope the book will prove especially useful to research workers in related subjects, to research students, and perhaps as source material for the preparation of lectures. The examples have been chosen to illustrate the theoretical basis of the topics rather than attempt a complete coverage. Professors Wagner and Troe describe the remarkable progress made in recent years in measuring dissociation rates for small molecules. Tests ofunimolecular reaction theories are usually made in the 'fall-off' region of pressure: the kinetics change from first order to second order as the pressure is reduced. For large molecules this region lies below atmospheric pressure and is relatively easily accessible. For molecules with four or less atoms, however, the fall-off region lies well above atmospheric pressure: it has been explored using the high pressure shock tube techniques developed by the authors.

Book Description
The Present Edition Is A Revised And Enlarged Edition Of The Earlier Book (Chemical Kinetic Methods, Principles Of Relaxation Techniques And Applications). Four New Chapters, Dealing With The Fast Kinetic Methods, Viz. Flow Methods Pulse Radiolysis, Flash Photolysis And Fluoresence Quenching Method Have Been Added With A View To Bring More Such Methods In One Comprehensive Volume. As These Techniques Do Not Come Under The Category Of Relaxation Methods, The Title Of The Book Has Been Generalised As Chemical Kinetic Methods, Principles Of Fast Reaction Techniques And Applications . Some New Features Of This Book Are (I) The Inclusion Of Worked Out Examples And (Ii) Addition Of More Practice Problems Supplementing The Earlier Ones In All Chapters (Except Chapters I And Xi).It Is Hoped That Both These Features Will Be Welcomed By The Student Community Especially, Postgraduate Students Of Chemistry Who Wish To Have A Comprehensive Understanding Of This Area Of Kinetics. The Addition Of Many Numerical Problems (Worked Out Examples And Practice Problems) Might Also Provide Teachers Of This Subject (Fast Kinetic Methods) As Well As Those Teaching A General Course On Chemical Kinetics With A Wider Choice In Selection Of Problems In Their Academic Work. It Is Fervently Hoped That The Book Will Be Welcomed By The Chemistry Faculty Of Various Universities, I.I.Ts And Other Academic Institutions In The Country As Well As By Other Academicians Who Are Interested In The Area Of Chemical Kinetics.

Book Description
During the last 30 years our knowledge and understanding of molecular processes has followed the development of increasingly sophisticated tech niques for studying fast reactions. Although the results are reported in papers and reviews, it is sometimes difficult for those not themselves active in these fields to find their way through the mass of published material. We hope that each book in this series will present a clear account of the present state of knowledge in a particular field of physical chemistry to research workers in related fields, to research students, and for the preparation of undergraduate and post-graduate lectures. Each chapter describes the theoretical develop ment of one area of study and the appropriate experimental techniques; the results presented are chosen to illustrate the theory rather than to attempt a comprehensive review. The first volume published in 1972 was concerned with the reactions of small molecules and free radicals in the gas phase. The development of flash photolysis in the 1950s paved the way by making it possible to generate free radicals in sufficient concentration for a spectroscopic" snapshot" to reveal their molecular structure. Their role in kinetic systems could then be followed directly, rather than be inferred from mechanism. The shock tube enabled gas mixtures to be heated to any desired temperature in a time which was shorter than subsequent chemical reactions. Discharge-flow methods enabled the reactions of atoms and free radicals to be studied directly.

Book Description
The past 25 years in chemical kinetics have seen major advances in studyiqg the mechanisms of complex chemical re actions, in particular free radical reactions. Many differ ent methods have been developed for quantitative studies of elementary chemical reactions. Thousands of rate constants have been measured, for hundreds of diverse chemical reac tions. It is becoming more and more difficult for the chemist to orient himself in the voluminous and rapidly growing liter ature of chemical reaction kinetics. This leads to major expenditures of time in searching out, collecting. and eval uating quantitative kinetic data; to unnecessary repetition (duplication) of research; and to a situation in which the rich material already accumulated in the field of chemical kinetics is very often not fully utilized in comparing, interpreting, and analyzing new experimental data. There is a pressing need for the creation of a series of handbooks on reaction rate constants. Such work was begun several years ago at the initiative of V. N. Kondrat'ev, and is now going forward under his direction at the Institute of Chemical Physics of the USSR Academy of Sciences. This book is devoted to liquid-phase, homolytic reactions. Part One contains data on monomolecular reactions in which molecules decompose to form radicals, as well as data on bi molecular and trimolecular reactions that form free radicals.

Book Description
Chemical Kinetics bridges the gap between beginner and specialist with a path that leads the reader from the phenomenological approach to the rates of chemical reactions to the state-of-the-art calculation of the rate constants of the most prevalent reactions: atom transfers, catalysis, proton transfers, substitution reactions, energy transfers and electron transfers. For the beginner provides the basics: the simplest concepts, the fundamental experiments, and the underlying theories. For the specialist shows where sophisticated experimental and theoretical methods combine to offer a panorama of time-dependent molecular phenomena connected by a new rational. Chemical Kinetics goes far beyond the qualitative description: with the guidance of theory, the path becomes a reaction path that can actually be inspected and calculated. But Chemical Kinetics is more about structure and reactivity than numbers and calculations. A great emphasis in the clarity of the concepts is achieved by illustrating all the theories and mechanisms with recent examples, some of them described with sufficient detail and simplicity to be used in general chemistry and lab courses. * Looking at atoms and molecules, and how molecular structures change with time. * Providing practical examples and detailed theoretical calculations* Of special interest to Industrial Chemistry and Biochemistry

Book Description
This book deals with a central topic at the interface of chemistry and physics—the understanding of how the transformation of matter takes place at the atomic level. Building on the laws of physics, the book focuses on the theoretical framework for predicting the outcome of chemical reactions. The style is highly systematic with attention to basic concepts and clarity of presentation. The emphasis is on concepts and insights obtained via analytical theories rather than computational and numerical aspects. Molecular reaction dynamics is about the detailed atomic-level description of chemical reactions. Based on quantum mechanics and statistical mechanics, the dynamics of uni- and bi-molecular elementary reactions are described. The book features a comprehensive presentation of transition-state theory which plays an important role in practice, and a detailed discussion of basic theories of reaction dynamics in condensed phases. Examples and end-of-chapter problems are included in order to illustrate the theory and its connection to chemical problems. The second edition includes updated descriptions of adiabatic and non-adiabatic electron-nuclear dynamics, an expanded discussion of classical two-body models of chemical reactions, including the Langevin model, additional material on quantum tunnelling and its implementation in Transition-State Theory, and a more thorough description of the Born and Onsager models for solvation.
