Book Description
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 Description
Ions and Ion Pairs and their Role in Chemical Reactions covers a wide spectrum of ion pairing phenomena. This book focuses on the structure, dynamics, and energetics of ions and ion pairs and their complexes with solvent molecules and ion coordinating ligands in the solid, liquid, and gaseous state. Organized into 12 chapters, this book begins with an overview of the theory and complications involved in dipole moment measurements in slightly conductive polar solvents. This text then explores the measurement of gas phase ion-molecule equilibria by special spectrometric methods. Other chapters consider the NMR experiments on potassium biphenyl, sodium biphenyl, and rubidium biphenyl, dissolved in different solvents. This book discusses as well the ion pair formation of some cyclic conjugated carbanions and nitranions. The final chapter deals with the information obtained from relaxation measurements on processes such as ionic dissociation, aggregation, and solvent separation. This book is a valuable resource for chemists, organic chemists, and quantum chemists.

Book Description
Recent advances in the study of structural and dynamic properties of solutions have provided a molecular picture of solute-solvent interactions. Although the study of thermodynamic as well as electronic properties of solutions have played a role in the development of research on the rate and mechanism of chemical reactions, such macroscopic and microscopic properties are insufficient for a deeper understanding of fast chemical and biological reactions. In order to fill the gap between the two extremes, it is necessary to know how molecules are arranged in solution and how they change their positions in both the short and long range. This book has been designed to meet these criteria. It is possible to develop a sound microscopic picture for reaction dynamics in solution without molecular-level knowledge of how reacting ionic or neutral species are solvated and how rapidly the molecular environment is changing with time. A variety of actual examples is given as to how and when modern molecular approaches can be used to solve specific solution problems. The following tools are discussed: x-ray and neutron diffraction, EXAFS, and XANES, molecular dynamics and Monte Carlo computer simulations, Raman, infrared, NMR, fluorescence, and photoelectron emission spectroscopic methods, conductance and viscosity measurements, high pressure techniques, and statistical mechanics methods. Static and dynamic properties of ionic solvation, molecular solvation, ion-pair formation, ligand exchange reactions, and typical organic solvents are useful for bridging the gap between classical thermodynamic studies and modern single-molecule studies in the gas phase. The book will be of interest to solution, physical, inorganic, analytical and structural chemists as well as to chemical kineticists.
