Available in PDF, EPUB and Kindle. Book excerpt: Activity in any theoretical area is usually stimulated by new experimental techniques and the resulting opportunity of measuring phenomena that were previously inaccessible. Such has been the case in the area under consideration he re beginning about fifteen years aga when the possibility of studying chemical reactions in crossed molecular beams captured the imagination of physical chemists, for one could imagine investigating chemical kinetics at the same level of molecular detail that had previously been possible only in spectroscopic investigations of molecular stucture. This created an interest among chemists in scattering theory, the molecular level description of a bimolecular collision process. Many other new and also powerful experimental techniques have evolved to supplement the molecular be am method, and the resulting wealth of new information about chemical dynamics has generated the present intense activity in molecular collision theory. During the early years when chemists were first becoming acquainted with scattering theory, it was mainly a matter of reading the physics literature because scattering experiments have long been the staple of that field. It was natural to apply the approximations and models that had been developed for nuclear and elementary particle physics, and although some of them were useful in describing molecular collision phenomena, many were not.

Download or read book Advances in Molecular Vibrations and Collision Dynamics written by and published by Elsevier. This book was released on 1998-09-25 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on molecular clusters, bound by van der Waals interactions and hydrogen bonds. Twelve chapters review a wide range of recent theoretical and experimental advances in the areas of cluster vibrations, spectroscopy, and reaction dynamics. The authors are leading experts, who have made significant contributions to these topics. The first chapter describes exciting results and new insights in the solvent effects on the short-time photo fragmentation dynamics of small molecules, obtained by combining heteroclusters with femtosecond laser excitation. The second is on theoretical work on effects of single solvent (argon) atom on the photodissociation dynamics of the solute H2O molecule. The next two chapters cover experimental and theoretical aspects of the energetics and vibrations of small clusters. Chapter 5 describes diffusion quantum Monte Carlo calculations and non additive three-body potential terms in molecular clusters. The next six chapters deal with hydrogen-bonded clusters, reflecting the ubiquity and importance of hydrogen-bonded networks. The final chapter provides the microscopic theory of the dynamics and spectroscopy of doped helium cluster, highly quantum systems whose unusual properties have been studied extensively in the past couple of years.
Book Synopsis Lasers and Chemical Change by : A. Ben-Shaul
Download or read book Lasers and Chemical Change written by A. Ben-Shaul and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers and chemical change is the study of radiation and molecules in dis equilibrium. The distinguishing feature of such systems is the extreme de parture from thermal equilibrium: the radiation is usually confined to a narrow frequency range, is well coll imated, and is far brighter than black body radiation; the chemical composition and also the distribution of mole cules over their different energy states are often markedly displaced from that expected at equilibrium. Such systems can be used as a source of laser radiation and, reversedly, lasers can rapidly and selectively displace mole cular systems from equilibrium. The subsequent evolution of the initially prepared state can then be monitored - again using lasers. One purpose of this book is to introduce the concepts required to d- cuss systems of radiation and molecules in disequilibrium. These include the physics of (laser) radiation and of radiation-matter interaction and molecular structure and spectroscopy. Excellent textbooks of these topics are available and our survey (in Chap. 3) is only intended to accent the es sential points, with special reference to atomic and molecular radiation physics. Considerably more attention is given to the topic of disequilibrium in chemical systems (Chap. 2). In particular we consider both inter- and intra molecular dynamics with special reference to energy requirements and energy disposal in chemical reactions and to what goes on in between - intramole cular energy migration.

Available in PDF, EPUB and Kindle. Book excerpt: Activity in any theoretical area is usually stimulated by new experimental techniques and the resulting opportunity of measuring phenomena that were previously inaccessible. Such has been the case in the area under consideration here beginning about fifteen years ago when the possibility of studying chemical reactions in crossed molecular beams captured the imagination of physical chemists, for one could imagine investigating chemical kinetics at the same level of molecular detail that had previously been possible only in spectroscopic investigations of molecular stucture. This created an interest among chemists in scattering theory, the molecular level description of a bimolecular collision process.

It was natural to apply the approximations and models that had been developed for nuclear and elementary particle physics, and although some of them were useful in describing molecular collision phenomena, many were not. The most relevant treatise then available to students was Mott and Massey's classic The Theory of Atomic Collisions, * but, as the title implies, it dealt only sparingly with the special features that arise when at least one of the collision partners is a molecule.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research has been to determine the effect of selective electronic and vibrational excitation on energy transfer and reaction rates in simple molecular systems. The combined use of selective excitation and final state resolution has demonstrated that a broad variety of behavior is exhibited in collisions of simple chemical species. The principal results can be grouped into three sets: (1) Influence of Reagent Energy on Chemical Reactions, (2) Vibrational Relaxation vs Reaction, and (3) Vibrational Relaxation in Polyatomic Systems.

Book Synopsis Theory of Molecular Collisions by : Gabriel G. Balint-Kurti
Download or read book Theory of Molecular Collisions written by Gabriel G. Balint-Kurti and published by Royal Society of Chemistry. This book was released on 2015-07-03 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost 100 years have passed since Trautz and Lewis put forward their collision theory of molecular processes. Today, knowledge of molecular collisions forms a key part of predicting and understanding chemical reactions. This book begins by setting out the classical and quantum theories of atom-atom collisions. Experimentally observable aspects of the scattering processes; their relationship to reaction rate constants and the experimental methods used to determine them are described. The quantum mechanical theory of reactive scattering is presented and related to experimental observables. The role of lasers in the measurement and analysis of reactive molecular collisions is also discussed. Written with postgraduates and newcomers to the field in mind, mathematics is kept to a minimum, and readers are guided to appendices and further reading to gain a deeper understanding of the mathematics involved.

Book Synopsis Molecular Collision Dynamics by : J.M. Bowman
Download or read book Molecular Collision Dynamics written by J.M. Bowman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph covers a broad spectrum of topics in the very broad field of gas phase molecular collision dynamics. The Introduction previews each of the four fol lowing topics and attempts to sew them together with a common thread. In addition, a brief review of quantum reactive scattering is given there along with some gen eral remarks which highlight the difficulties in doing quantum reactive scatter ing calculations. The chapters are all written by theoreticians who are, of course, experts in the subjects they have written about. Three chapters, the ones by Secrest, Schatz, and the one by Schinke and Bowman deal with non-reactive atom-molecule scattering. Col lectively, they describe nearly the full breadth of scattering methods in use to day, from fully quantum mechanical to semiclassical and quasiclassical. The chapter by Baer is the only one dealing with quantum reactive scattering with the additional complexity of the coupling of two potential energy surfaces. The one simplifying feature of the treatment is that the reaction is constrained to be collinear. Overall, this monograph is mainly a review of the recent advances in the field of molecular collision dynamics, with, however, a considerable amount of new material. It is hoped that workers and students in the field will find reading the mono graph both enlightening and enjoyable.

Download or read book Energetics and Collision Dynamics of Electronic Transition Lasers written by H. Harvey Michels and published by . This book was released on 1981 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the partition of energy between the products of a chemical reaction is fundamental to the understanding of the dynamics of collisional reactions. Atom-atom and atom-molecule reactions that yield vibrationally excited diatomic molecules are of particular scientific and military interest. An understanding of the dynamics of the simplest of these reactions is a prerequisite for understanding more complicated gas phase reactions. A knowledge of at least limited regions of potential energy surfaces is of importance in analyzing the vibrational and rotational relaxation rates and can be utilized in a predictive fashion. In the low energy regime there are little data available on collision processes and experimental measurements are difficult. Thus, a program to develop theoretical techniques and construct computer programs for calculating potential energy surfaces and kinetic cross sections for simple collision processes is appropriate. The potential energy surfaces include both atom-atom and atom-diatom systems with special emphasis on molecular reactions yielding electronically excited products which have potential as visible or UV chemical lasers. These systems include metal oxides and halides, metal excimers and the noble gas-halides.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical and Biochemical Applications of Lasers, Volume IV focuses on the practical applications of standard commercial laser systems. This book examines the structural studies of DNA by fluorescence microscopy and discusses photochemistry and structural spectroscopy. Organized into eight chapters, this volume starts with an overview of a few cases of laser-induced fluorescence studies of biological molecules. This text then examines the sharp fluorescence spectra of complex molecules in solids that are obtained when a narrow-band laser selectively excites molecules in particular sites. Other chapters describe the theory and application of resonance Raman spectroscopy to various biological systems. This book provides as well a thorough treatment of coherent anti-Stokes Raman spectroscopy and its application in combustion diagnostics and analytical chemistry. The final chapter explores laser control of the sequential photochemical reaction of the drug psoralen with the two strands of the DNA double helix. Physicists, chemists, electrochemists, and chemical engineers will find this book useful.
