内容説明

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.

内容説明

In this volume 28 papers are presented. They cover all the fields studied with ion cyclotron resonance today, including reviews on important fields as well as short contributions on special topics. This report is devided into four parts: 1. Detailed studies on simple molecules, 2. Systematic studies of the ion chemistry, 3. Spectrometer development and 4. Theory. The plan to edit a progress report of the complete field was projected at the 2nd International Symposium on Ion Cyclotron Resonance Spectrometry, held at the Akademie der Wissenschaften und der Literatur, Mainz, March, 1981. Most of the contributions were written in late 1981 or in 1982.
