The investigation of the elementary reactions of reactive intermediate species began about half a centruy ago with the advent of free radical kinetics as an active area of chemical research. In spite of the relatively greater ease of detection of a species carrying an electrical charge, and the fact that organic chemists had for decades postulated mechanisms involving ionic intermediates, the systematic study of the elementary reactions of ions was delayed for more than twenty years after the first beginnings of free radical kinetics. Even at this writing, in 1978, the word "kinetics" is considered by many chemists to be synomomous with "kinetics of neutral species". Yet in spite of the relatively late start and separation from the mainstream of kinetics, the field of ion physics and chemistry is fluorishing, and growing at an ever faster pace. Instrumentalists devise ever more sophisticated apparatuses with capabilities of delving into nearly every aspect of the interactions between ions and molecules. Even satellites orbiting the earth are now being used effectively to determine rate coefficients of ionospheric ion-neutral reactions, some of which can not as yet be measured in the laboratory.

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.

State-Selected and State-to-State Ion-Molecules Reaction Dynamics details the recent experimental and theoretical accomplishments in the field to date by some of its foremost researchers and theorists. Divided into two parts, each of which separately describe the experimental and theoretical aspects of the field, State-Selected and State-to-State Ion-Molecule Reaction Dynamics is an accessible, well organized look at a highly useful and emerging chemical specialty. Part 1, "Experiment," contains eight in-depth studies, which illustrate the key experimental work being done in the field today: Chapter 1 provide a comprehensive review of the theory and application of inhomogeneous rf fields for the study of the dynamics of low-energy ion-molecules processes Chapter 2 describes the application of multiphoton ionization (MPI) for the preparation of reactant ion states Chapter 3 reviews the application of MPI schemes for state specific cross-section measurements involving transition metal cations Chapter 4 describes the development of the threshold photoelectron secondary ion coincidence (TESICO) method Chapter 5 presents the conceptual and practical aspects of a multicoincidence technique Chapter 6 details the experimental results obtained using the photoionization and differential reactivity methods Chapter 7 reviews the several recent crossed beam studies of charge transfer and collision-induced dissociation systems involving atomic and molecular ions Chapter 8 is a survey of 15 years of high resolution crossed beam scattering of protons with atoms, diatoms, and poly-atomic molecules State-Selected and State-to-State Ion-Molecule Reaction Dynamics, Part 1: Experiment offers professionals a true state-of-the-science look at this fascinating and increasingly influential subject.

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.
