Ion Cyclotron Resonance Spectrometry

In this volume, for the first time, a dozen of papers is collected dealing with almost all important aspects of ion cyclotron resonance spectrometry. The ICR technique was developed very rapidly in the last two decades. It seems to the editors that the method is now established well enough to dedicate a progress report to it. This report is devided into three parts: The first articles pre sent new developments in the theory of ICR spectrometry. They are fol~ lowed by papers on r.ecent developments of the experimental technique. About half of the volume is dedicated to applications of ICR spectrome try to reactivity, reaction mechanism and structure in the chemistry of thermal ions. The editors are indebted to Mrs. A. Tin for typewrfting most of the manuscript and to Mrs. E. Jacke for reproduction of Figures appearing in the volume.
