This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Reaction rate constants have been acquired for the transition metal ion assisted decomposition of various organic molecules, and their deuterium labeled analogs in the gas phase. The metal ion activates organic bonds and mediates the formation of products. Thus, the transition metal cation lowers the bond activation energy requirements in these decomposition reactions making these systems model for catalysis. Catalytic reaction kinetics are not well understood and it is hoped that the resolved study of simpler catalytic models will further the development of the theoretical tools necessary to describe such mechanistic behavior at the molecular level. Reaction rate constants for these model systems are measured using a custom-built molecular beam apparatus. The clusters are formed under supersonic expansion conditions and are bound by the charge-dipole electrostatic interaction between a transition metal cation and a polar organic molecule. The unimolecular decomposition occurs upon laser photon absorption by the jet-cooled cluster yielding a stable neutral molecule and corresponding ion. This dissertation will focus on the unimolecular decomposition kinetics of the Co+-Acetone cluster and its deuterium labeled analog. Rate constants are measured at well resolved cluster internal energies. The kinetic isotope effect (KIE) for each measurement was determined. Results are compared to the similar Ni+-Acetone decomposition reactions, where the KIE was also measured. These two similar systems present rather different dissociation dynamics. Arguments based on the electronic structure of each ion explain this unique behavior between these similar systems. DFT calculations are made on most systems presented in this dissertation. The most likely geometries and relative energies of the reactants, intermediates and products are determined. Such information specifies aspects of the reaction coordinate and leads to suggestions of mechanisms. This was primarily applied in the final chapter of this dissertation where preliminary results of Ni+-assisted decomposition of cyclopentanone are presented. This system represents the group's first study of a ring-opening reaction.

Available in PDF, EPUB and Kindle. Book excerpt: Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.

Download or read book Introduction to Coordination Chemistry written by Geoffrey A. Lawrance and published by John Wiley & Sons. This book was released on 2013-03-15 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the heart of coordination chemistry lies the coordinate bond, in its simplest sense arising from donation of a pair of electrons from a donor atom to an empty orbital on a central metalloid or metal. Metals overwhelmingly exist as their cations, but these are rarely met ‘naked’ – they are clothed in an array of other atoms, molecules or ions that involve coordinate covalent bonds (hence the name coordination compounds). These metal ion complexes are ubiquitous in nature, and are central to an array of natural and synthetic reactions. Written in a highly readable, descriptive and accessible style Introduction to Coordination Chemistry describes properties of coordination compounds such as colour, magnetism and reactivity as well as the logic in their assembly and nomenclature. It is illustrated with many examples of the importance of coordination chemistry in real life, and includes extensive references and a bibliography. Introduction to Coordination Chemistry is a comprehensive and insightful discussion of one of the primary fields of study in Inorganic Chemistry for both undergraduate and non-specialist readers.

Download or read book Physical Chemistry of Cold Gas phase Functional Molecules and Clusters written by Takayuki Ebata and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes advanced research on the structures and photochemical properties of polyatomic molecules and molecular clusters having various functionalities under cold gas-phase conditions. Target molecules are crown ethers, polypeptides, large size protonated clusters, metal clusters, and other complex polyatomic molecules of special interest. A variety of advanced frequency and time-domain laser spectroscopic methods are applied. The book begins with the principle of an experimental setup for cold gas-phase molecules and various laser spectroscopic methods, followed by chapters on investigation of specific molecular systems. Through a molecular-level approach and analysis by quantum chemical calculation, it is possible to learn how atomic and molecular-level interactions (van der Waals, hydrogen-bonding, and others) control the specific properties of molecules and clusters. Those properties include molecular recognition, induced fitting, chirality, proton and hydrogen transfer, isomerization, and catalytic reaction. The information will be applicable to the design of new types of functional molecules and nanoparticles in the broad area that includes applied chemistry, drug delivery systems, and catalysts.

Download or read book Principles of Organometallic Chemistry written by G. E. Coates and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Organometallic Compounds (1960) was used not only by specialists but also as an undergraduate textbook. The third edition, recently published in two volumes, is about three times the length of the second and contains considerably more factual material than is appropriate for a student textbook. Therefore we believe that a shorter treatment would be welcome. In planning this book the authors have emphasized matters more of prin ciple than of detail, and have included in the first two chapters some general discussion of the properties and syntheses of organometallic compounds that is not to be found in the larger work. Some aspects of the organic chemistry of arsenic, and of silicon with particular reference to silicone polymers, are also included. Most university teachers of chemistry are becoming seriously concerned about the relentless increase in the amount and complexity of the material that is squeezed into undergraduate chemistry courses. With this in mind the authors have tried to cut detail to a minimum, but readers will find that the relative amount presented varies considerably between the various topics discussed. In general the treatment is more extensive than usual only if either or both of these conditions are met: (1), the subject has significant bearing on other major branches of chemistry including im portant industrial processes; (2), the topic is commonly misunderstood or found to be confusing.
