Gas phase ion chemistry is a broad field that has many applications and which encompasses various branches of chemistry and physics. "Advances in Gas Phase Ion Chemistry, Volume 4, " describes innovative ways of studying reactions as well as the application of unique apparatuses to problems in this field. This volume contains a series of chapters, in the general area of gas phase chemistry and physics, which are at the cutting edge of research.
The chapters are not meant to be general reviews, but focus on the author's own work. They focus on both experimental and theoretical work, which gives a balance to the volume. Applications are included to appeal to a wider audience and to broaden the knowledge of the more fundamentally inclined. An application to environmental pollution monitoring and medical monitoring of breath is included. With successive volumes, the coverage broadens to include more current research in the title area.
The book is aimed at graduate researchers, university faculty and graduates in industry. The editors have made a specific effort to include contributions from those relatively new to the field, which brings in new ideas and perspectives, as well as those more established workers, who bring a wealth of experience.

Gas-phase ion chemistry is a broad field which has many applications and which encompasses various branches of chemistry and physics. An application that draws together many of these branches is the synthesis of molecules in interstellar clouds. This was part of the motivation for studies on the neutralization of ions by electrons and on isomerization in ion-neutral associations. The results of investigations of particular aspects of ion dynamics are presented in this volume. Solvation in ion-molecule reactions is discussed and extended to include multiply charged ions by the application of electrospray techniques. This volume also provides a wealth of information on reaction thermodynamics which is critical in determining reaction spontaneity and availability of reaction channels. More focused studies are also presented towards the end of this volume, relating to the ionization process and its nature.
