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.

Energetics of Organic Free Radicals
Author: José A. Martinho Simões
Publisher: Springer Science & Business Media
ISBN: 9780751403787
Category : Science
Languages : en
Pages : 328
Book Description
The current volume consists of eight chapters which interweave various aspects of the structure, energetics and reactivity of organic free radicals, all combining pedagogical insights with current research. The first is by Walling in which a personalized overview is given by one of the modern pioneers of the discipline. In the next two chapters, Tsang, and Traeger and Kompe, present key thermochemical and kinetic quantities from the complementary vantage points of the studies of neutral and cationic species. The fourth chapter by Francisco and Montgomery discusses the armamentarium of modern theory as applied to species with unpaired electrons, while the next chapter by Goodman presents the theory, methodology and results from photoacoustic calorimetry, a novel and powerful experimental technique. Martinho Simoes and Minas da Piedade interrelate organometallic and free radical chemistry, while Greenberg and Liebman consider resonance energy and rearrangements as applied to small molecules and enzyme cofactors alike. The volume ends with the chapter by Tanko and Suleman, which describes the surprising and diverse solvent effects which modulate free radical chem istry. This volume will make it apparent to entry-level graduate students and senior researchers alike that much is known and much remains to be done in both the qualitative understanding and quantitative insights of the chemistry of organic free radicals.

Chemical Kinetics
Author: Luis Arnaut
Publisher: Elsevier
ISBN: 0080469345
Category : Science
Languages : en
Pages : 563
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 4th edition of Handbook of Solvents, Volume 1, contains the most recent findings and trends in solvent applications. It is a comprehensive survey of the science of solvents and their properties, covering all aspects of solvent behavior that are relevant to their use in chemical and related industries including agricultural and technical processes, inorganic synthesis and materials chemistry, and more. Divided into two volumes, this first volume covers high-level information on the physical chemical properties of the most relevant solvent systems. Each chapter is focused on a specific aspect of solvent properties that determine its selection, such as the effect on properties of solutes and solutions, properties of different groups of solvents, and the summary of their applications' effect on health and the environment (given in tabulated form). Also covered is swelling of solids in solvents, solvent diffusion and drying processes, nature of the interaction of solvent and solute in solutions, acid-base interactions, the effect of solvents on spectral and other electronic properties of solutions, the effect of solvents on the rheology of the solution, aggregation of solutes, permeability, molecular structure, crystallinity, configuration, conformation of dissolved high molecular weight compounds, and the effect of solvents on chemical reactions and reactivity of dissolved substances. With insight from specialists in a broad array of different areas and written with an interdisciplinary audience in mind, this thoroughly revised 4th edition provides readers with a complete overview of all the organic solvents available for industrial applications today. The book contains numerous references to key sources of more detailed information, and together with Handbook of Solvents Volume 2: Use, Health, and Environment; Databook of Green Solvents; and Databook of Solvents, represents the most comprehensive and up-to-date information ever published on solvents. - Provides key insights that will help engineers and scientists select the best solvent for the job - Includes practical information and ideas on how to improve existing processes involving solvents - Presents the latest advances in solvent technology and their applications
