Book Description
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.

Book Description
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.

Book Description
Ion Mobility Spectrometry IMS as provided the US Army with capabilities for ultrasensitive detection of chemical warfare agents and this technology is undergoing continued development and refinement today as a miniaturized detector of warfare agents. The basis for response in this technology is gas phase ion chemistry at ambient atmosphere; however, no broad framework has existed for understanding this chemistry and no predictive ans interpretative capabilities have existed for mobility spectra. This has meant that a new chemical agent deployed against US soldiers could conceivably be unrecognized by existing methods. A comprehensive model for the prediction and interpretation of mobility spectra was created here and tools are available to understand and predict spectra for the first time in history of modern analytical mobility spectrometry. Predictive capabilities are rooted in assessments of ion stability, ion lifetimes, times for ion drift, temperature and moisture. Interpretative capabilities were attained through neural networks and spectral assignments succeeded on the basis of previously uncharacterized fragmentation of ions at ambient atmosphere. The results from this work demonstrated the possibility that an unknown or unfamiliar chemical can be categorized or recognized by chemical class.
