Book Synopsis Dynamics of Ion-Molecule Complexes by : William L Hase
Download or read book Dynamics of Ion-Molecule Complexes written by William L Hase and published by Elsevier. This book was released on 2016-07-29 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Classical Trajectory Methods, Volume 2: Dynamics of Ion-Molecule Complexes is a seven-chapter text that covers the considerable advances in the experimental and theoretical aspects of ion-molecular complexes, with particular emphasis on the dynamics and kinetics of their formation and ensuing unimolecular dissociation. This text also considers the development and testing of theoretical models for these formation and decomposition processes. The opening chapters discuss photoelectron photoion coincidence, ion cyclotron resonance, and crossed molecular beam studies of metastable ion-molecule complexes formed in ion-molecule collisions. These experimental studies involve comparisons with the predictions of statistical models, such as the Rice-Ramsperger-Kassel-Marcus and phase space theories, and comparisons with the reaction dynamics predicted by classical trajectory calculations. The succeeding chapter describes the double-well model for ion-molecular reactions taking place on a potential energy surface with a central barrier that separates two potential energy minima. These topics are followed by reviews of the quantum chemical calculation and reaction path Hamiltonian analysis of SN2 reactions, the transition state theory for ion-dipole and ion-quadrupole capture, and the capture and dynamical models for ion-molecule association to form a complex. The remaining chapters consider the temperature dependence of ion-molecule reactions, which proceed on a surface with many potential energy minima, specifically the ability to establish asymptotic limits for the reaction efficiency dependent upon the number of potential minima and the above relative probabilities. This book is of great value to experimental and theoretical chemists and physicists.

Book Synopsis High-dimensional Partial Differential Equations in Science and Engineering by : André D. Bandrauk
Download or read book High-dimensional Partial Differential Equations in Science and Engineering written by André D. Bandrauk and published by American Mathematical Soc.. This book was released on 2007-01-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-dimensional spatio-temporal partial differential equations are a major challenge to scientific computing of the future. Up to now deemed prohibitive, they have recently become manageable by combining recent developments in numerical techniques, appropriate computer implementations, and the use of computers with parallel and even massively parallel architectures. This opens new perspectives in many fields of applications. Kinetic plasma physics equations, the many body Schrodinger equation, Dirac and Maxwell equations for molecular electronic structures and nuclear dynamic computations, options pricing equations in mathematical finance, as well as Fokker-Planck and fluid dynamics equations for complex fluids, are examples of equations that can now be handled. The objective of this volume is to bring together contributions by experts of international stature in that broad spectrum of areas to confront their approaches and possibly bring out common problem formulations and research directions in the numerical solutions of high-dimensional partial differential equations in various fields of science and engineering with special emphasis on chemistry and physics.

Book Synopsis Time-Resolved Mass Spectrometry by : Pawel L. Urban
Download or read book Time-Resolved Mass Spectrometry written by Pawel L. Urban and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time is an important factor in physical and natural sciences. It characterizes the progress of chemical and biochemical processes. Mass spectrometry provides the means to study molecular structures by detecting gas-phase ions with the unique mass-to-charge ratios. Time-resolved mass spectrometry (TRMS) allows one to differentiate between chemical states that can be observed sequentially at different time points. Real-time mass spectrometric monitoring enables recording data continuously with a specified temporal resolution. The TRMS approaches – introduced during the past few decades – have shown temporal resolutions ranging from hours down to microseconds and beyond. This text covers the key aspects of TRMS. It introduces ion sources, mass analyzers, and interfaces utilized in time-resolved measurements; discusses the influence of data acquisition and treatment; finally, it reviews most prominent applications of TRMS – in the studies of reaction kinetics and mechanism, physicochemical phenomena, protein structure dynamics, biocatalysis, and metabolic profiling. It will assist science and engineering students to gain a basic understanding of the TRMS concept, and to recognize its usefulness. In addition, it may benefit scientists who conduct molecular studies in the areas of chemistry, physics and biology.
Book Synopsis Structure and Dynamics of Weakly Bound Molecular Complexes by : Alfons Weber
Download or read book Structure and Dynamics of Weakly Bound Molecular Complexes written by Alfons Weber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of weakly bound molecular complexes has in recent years brought this field of investigation to the forefront of physical and chemical research. The scope of the subject is wide and different terminology and nomenclature is current among the various subspecialties. Thus, the term "metal cluster" often connotes to the organic chemist a metal-organic compound, while the physicist will more likely think of groups of metal atoms held together by weak interatomic forces. Aggregates, clusters, complexes, van der Waals molecules, hydrogen-bonded molecules, etc. are terms currently in use, sometimes interchangeably while other times with well defined and mutually exclusive meanings. The subjects of this volume are the free, isolated vim der Waals and hydrogen-bonded molecules. Owing to the present state of experimental knowledge these are mostly dimers, i. e. , entities formed by two strongly bound molecules, an atom and a molecule, or two atoms held together by the weak hydrogen-bonding, or the still weaker van der Waals forces. Weakly bound complexes formed of more than two strongly bound sub-units, i. e. , trimers, tetramers, etc. , are now coming within reachof experimental observation and several papers in this book deal with them. The study of van der Waals and hydrogen-bonded interactions has been pursued for several decades. Most of these ,investigations have, however, dealt with systems in the condensed phase in which bulk effects are commingled with and therefore mask the weak binary interactions.

Book Synopsis Advances in Gas Phase Ion Chemistry by : N.G. Adams
Download or read book Advances in Gas Phase Ion Chemistry written by N.G. Adams and published by Elsevier. This book was released on 1998-04-23 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas-phase ion chemistry is a broad field which has many applications and which encompasses various branches of chemistry and physics. An application that draws together many of these branches is the synthesis of molecules in interstellar clouds. This was part of the motivation for studies on the neutralization of ions by electrons and on isomerization in ion-neutral associations. The results of investigations of particular aspects of ion dynamics are presented in this volume. Solvation in ion-molecule reactions is discussed and extended to include multiply charged ions by the application of electrospray techniques. This volume also provides a wealth of information on reaction thermodynamics which is critical in determining reaction spontaneity and availability of reaction channels. More focused studies are also presented towards the end of this volume, relating to the ionization process and its nature.
Book Synopsis The Synergy Between Dynamics and Reactivity at Clusters and Surfaces by : L.J. Farrugia
Download or read book The Synergy Between Dynamics and Reactivity at Clusters and Surfaces written by L.J. Farrugia and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analogy between the chemistry of molecular transition metal clusters and the processes of chemisorption and catalysis at metal surfaces (the Cluster Surface analogy) has for a number of years provided an interplay between experimental and theoretical inorganic and physical chemists. This collaborative approach has born fruit in the use of well defined modes of metal-ligand bonding in discrete molecular clusters, models for metal-ligand binding on surfaces. Some of the key topics discussed in The Synergy between Dynamics and Reactivity at Clusters and Surfaces are: (1) Mechanisms of the fluxional behaviour in clusters in the liquid phase and the connections with diffusion processes on extended surfaces. The role of metal-metal bond breaking in diffusion. (2) Analogies in the structure of chemisorbed species and related ligands on metallic clusters. (3) Analogies between benzene surface chemistry on extended metal surfaces and on metal surfaces in molecular cluster compounds with particular reference to structural distortions. (4) The role of mobile precursors for dissociation of chemisorption on extended metals and on clusters. Are there analogies in the ligand attachment during cluster compound synthesis? (5) The role of defect sites on metal surfaces in catalyzing chemical reactions and the connection to the special bonding properties of sites on metal clusters having lowest metal-metal coordination. (6) The size of metal clusters needed to mimic surface phenomena on bulk metal surfaces. Different sites needed for different phenomena.

Book Synopsis Ion-Molecule Reactions by : J. Franklin
Download or read book Ion-Molecule Reactions written by J. Franklin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: After a few faint stirrings of interest in ion-molecule reactions during the early days of mass spectrometry, the subject was almost completely neglected for many years. There was a renascence of interest in the subject following pioneering experiments by Tal'roze in Russia and independently by Steven son and Schissler and Field, Franklin, and Lampe in this country. Since that time, interest in the subject has continued to grow and the number of papers published to expand almost exponentially during the past 15 years. The result is a body of literature that is now almost beyond any single individual's capacity for encompassing in his reading and research activities. Thus, it seemed timely to prepare a book giving in some detail a comprehen sive review of the field. Ideally, such a book would be written by one or possibly two authors. Unfortunately, the sheer bulk and variety of the studies of ion-molecule reactions has made it impractical for a single person to prepare a book on the subject in a time that would permit it to be issued before the material covered was obsolete. Consequently, the only practical, although surely not the ideal, solution is to issue a multiauthor volume. The present book represents our best efforts to accomplish this goal. We have secured from 18 authors material representing the most advanced work in the field and the resulting compilation is presented herein.
