The first comprehensive collection of all the major techniques used to study gas phase interactions is presented in this volume. With complete coverage of what a given technique can accomplish, its advantages and disadvantages, the book is designed to teach advanced students and researchers entering the field how to investigate a broad range of topics. Included is coverage of traditional topics such as ion cyclotron resonance, as well as more recent innovations, including Fourier transform mass spectrometry and ionic cluster studies. Several diagrams of instrumentation and examples of experimental data are also provided.

Gas Phase Ion Chemistry, Volume 2 covers the advances in gas phase ion chemistry. The book discusses the stabilities of positive ions from equilibrium gas-phase basicity measurements; the experimental methods used to determine molecular electron affinities, specifically photoelectron spectroscopy, photodetachment spectroscopy, charge transfer, and collisional ionization; and the gas-phase acidity scale. The text also describes the basis of the technique of chemical ionization mass spectrometry; the energetics and mechanisms of unimolecular reactions of positive ions; and the photodissociation of gas-phase ions. The applications of molecular beam techniques to the study of ion-molecule collisions; as well as the variational treatment of charge transfer reactions are also encompassed. Chemists and biochemists will find the book invaluable.

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.

The book includes 19 selected contributions presented at the 21st Evolutionary Biology Meeting, which took place in Marseille in September 2017. The chapters are grouped into the following five categories: · Genome/Phenotype Evolution · Self/Nonself Evolution · Origin of Biodiversity · Origin of Life · Concepts The annual Evolutionary Biology Meetings in Marseille serve to gather leading evolutionary biologists and other scientists using evolutionary biology concepts, e.g. for medical research. The aim of these meetings is to promote the exchange of ideas to encourage interdisciplinary collaborations. Offering an up-to-date overview of recent findings in the field of evolutionary biology, this book is in invaluable source of information for scientists, teachers and advanced students.

Mass Spectrometry of Organic Ions covers the underlying theories and major applications of mass spectrometry. This 13-chapter book starts with a survey of the mechanisms by which organic ions can decompose and rearrange, as well as the generalized concept in terms of physical-organic chemistry. The discussion then shifts to the advantages and potential of mass spectrometry in structure determination by the elucidation of the empirical formulas of organic ions. Considerable chapters are devoted to the detailed correlations and mechanisms of the mass spectra of long-chain esters, alkylbenzenes, a variety of natural products, aliphatic compounds, and terpenes. The remaining chapters demonstrate the illustrative power of mass spectrometry in structure of petroleum, which is composed of hydrocarbon mixture. This book will be of great benefit to organic and analytical chemists, scientists, and students.
