Book Description
"Solvent Effects on Reaction Ratyes and mechanisms" is a title that will conjure up visions of different things to different investigators in the field of reaction kinetics. The physical chemist will envision the effects on rates of reactions of dieelectric constant, viscosity, internal cohesion, and externaL pressure as these are iinfluenced by the solvent. The physical-organic chemist will perhaps call to mind acidity, basicity, hydrogen bonding, structure effects, electro-negativity, and solvating ability as related to the solvent. The stricly organic chemist may simplyt think in terms of a medium in which reactants can be made to form products merely because of solubility relations, and his choice of solvent may depend on the ease of obtaining in a reasonable length of time a relatively pure product by extraction or other procedures. And, in fact, the topic includes all these and much more. Some of the phenomena are merely recorded as experimental observations. Some factors are subject to theoretical explanation, but even when theoretically explained or mathematically formulated they may not be sufficiently dominant ti justify the applicaton of the theory. Other effects may not be subject to theoretical explanations but may be included in correlations that are widely applicable. The explanation of some effects may be purely conjectural, but at least give some satisfaction to the seekers of the answer to the question, why? The material presented in the following pages will run the gamut of all the above possibilities.

Book Description
Solvent Effects on Chemical Phenomena, Volume I discusses the developments in the understanding of solvent effects on chemical phenomena in solution. This five-chapter volume begins with a discussion on the general concepts of various solvation types, including positive and negative, inner and outer sphere, and mixed component. The subsequent chapter deals with the determination of the actual solvation number for single ions. A short list of the total effective hydration numbers of electrolytes determined from temperature dependence of proton shifts is also provided in this chapter. Another chapter presents a number of examples of the unusual properties of certain mixed aqueous systems. The solvent effects on reaction rates and mechanisms are highlighted in the concluding chapter. This chapter also covers various types of solvents, such as protic and dipolar aprotic. The enthalpy and entropy of activation in salvation and the Finkelstein reactions are also discussed. Research chemists and scientists, teachers, and students with courses in solution chemistry will greatly benefit from this volume.

Book Description
Now in its 4th edition, this book remains the ultimate reference for all questions regarding solvents and solvent effects in organic chemistry. Retaining its proven concept, there is no other book which covers the subject in so much depth, the handbook is completely updated and contains 15% more content, including new chapters on "Solvents and Green chemistry", "Classification of Solvents by their Environmental Impact", and "Ionic Liquids". An essential part of every organic chemist's library.

Book Description
Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Book Description
This book introduces the concepts, theory and experimental knowledge concerning solvent effects on the rate and equilibrium of chemical reactions of all kinds. It begins with basic thermodynamics and kinetics, building on this foundation to demonstrate how a more detailed understanding of these effects may be used to aid in determination of reaction mechanisms, and to aid in planning syntheses. Consideration is given to theoretical calculations (quantum chemistry, molecular dynamics, etc.), to statistical methods (chemometrics), and to modern day concerns such as "green" chemistry, where utilization and disposal of chemical waste or by-products in an environmentally safe way is as important as achieving the desired end products by all chemists nowadays. The treatment progresses from elementary to advanced material in straightforward fashion. The more advanced topics are not developed in an overly rigorous way so that upper-level undergraduates, graduates, and newcomers to the field can grasp the concepts easily.

Book Description
This book gathers original contributions from a selected group of distinguished researchers that are actively working in the theory and practical applications of solvent effects and chemical reactions. The importance of getting a good understanding of surrounding media effects on chemical reacting system is difficult to overestimate. Applications go from condensed phase chemistry, biochemical reactions in vitro to biological systems in vivo. Catalysis is a phenomenon produced by a particular system interacting with the reacting subsystem. The result may be an increment of the chemical rate or sometimes a decreased one. At the bottom, catalytic sources can be characterized as a special kind of surrounding medium effect. The materials involving in catalysis may range from inorganic components as in zeolites, homogenous components, enzymes, catalytic antibodies, and ceramic materials. . With the enormous progress achieved by computing technology, an increasing number of models and phenomenological approaches are being used to describe the effects of a given surrounding medium on the electronic properties of selected subsystem. A number of quantum chemical methods and programs, currently applied to calculate in vacuum systems, have been supplemented with a variety of model representations. With the increasing number of methodologies applied to this important field, it is becoming more and more difficult for non-specialist to cope with theoretical developments and extended applications. For this and other reasons, it is was deemed timely to produce a book where methodology and applications were analyzed and reviewed by leading experts in the field.
