Book Description
Electron Impact Phenomena and the Properties of Gaseous Ions, Revised Edition deals with data pertaining to electron impact and to molecular gaseous ionic phenomena. This book discusses electron impact phenomena in gases at low pressure that involve low-energy electrons, which result in ion formation. The text also describes the use of mass spectrometers in electron impact studies and the degree of accuracy obtained when measuring electron impact energies. This book also reviews relatively low speed electrons and the transitions that result in the ionization of the atomic system. This text then discusses diatomic molecules whose mass spectra can be interpreted using the Franck-Condon principle. This selection also presents some examples of ions in solution that resemble the gaseous ions formed by electron impacts. The energies of these gaseous ions can be the key to understanding the mechanisms of ionic reactions. These examples include the olefin addition reactions and catalytic cracking. This text will prove invaluable for research chemists, students, and professors in chemistry and related fields such as organic chemistry and electrochemistry.

Pages : 275
Book Description
Spectrometric Techniques, Volume IV discusses three widely diversified areas of spectrometric techniques. The book focuses on three spectrometric methods. Chapter 1 discusses the phenomenology and applications of Coherent Anti-Stokes Raman Spectroscopy (CARS), the most commonly used optical technique that exploit the Raman effect. The second chapter is concerned with diffraction gratings and mountings for the Vacuum Ultraviolet Spectral Region. Chapter 3 accounts the uses of mass spectrometry, detectors, types of spectrometers, and ion sources. Physicists and chemists will find the book a good reference material.
Interpretation of Mass Spectra of Organic Compounds
Author: Mynard HammingPublisher: Elsevier
ISBN: 0323143148
Category : Science
Languages : en
Pages : 709
Book Description
Interpretation of Mass Spectra of Organic Compounds outlines the basic instrumentation, sample handling techniques, and procedures used in the interpretation of mass spectra of organic compounds. The fundamental concepts of ionization, fragmentation, and rearrangement of ions as found in mass spectra are covered in some detail, along with the rectangular array and interpretation maps. Computerization of mass spectral data is also discussed. This book consists of nine chapters and begins with a historical overview of mass spectrometry and a discussion on some important developments in the field, along with a summary of interpretation objectives and methods. The following chapters focus on instruments, ion sources, and detectors; recording of the mass spectrum and the instrumental and sample variables affecting the mass spectrum; sample introduction systems; and fragmentation reactions. Correlations as applied to interpretations are also considered, with emphasis on applications of the branching rule as well as beta-bond and alpha-bond cleavages. Example interpretations, calculations, data-processing procedures, and computer programs are included. This monograph is intended for organic chemists, biochemists, mass spectroscopists, technicians, managers, and others concerned with the whys and wherefores of mass spectrometry.

Book Description
The present 18th volume differs from previous volumes insofar as, with the exception of two contributions, it is exclusively concerned with problems of a single field, namely Tropical Medicine. This was occasioned by the Internatio nal Symposium on the investigation and treatment of infectious tropical diseases held in Bombay in January 1974 and organized by the editor in collaboration with the Minister of Health of the State of Maharashtra, Dr. Rafiq Zakaria, the Director of the Hafl'kine Institute, Dr. B. Gaitonde, and with Dr. J. N. Banerjee, Dr. S. K. Bhattacharya and Mr. P. D'Souza. The Hafl'kine Institute celebrated on this occasion the 75th year of its existence and everyone entrusted with the organisation of the Symposium considered themselves fortunate to have been able to help in strengthening the contacts between Indian and foreign research workers, in the hope of, in this way, making a contribution to the fight against infectious tropical diseases. The editor hopes that the present 18th volume will represent comprehensive information on the topics treated at the Symposium; the 19th volume, which will soon appear, is concerned with the same area, so that the two volumes together should give a good picture of the many still unsolved problems. The editor would also like to take this opportunity of expressing his gratitude to his collaborator, Dr. A. Niif, who, as usual, performed valuable services in working over the manuscripts.

Pages : 592
Book Description
Electrostatic Propulsion focuses on issues, trends, and developments in electrostatic propulsion. The compilation is composed of technical papers primarily based on the symposium of the American Rocket Society held at the U. S. Naval Postgraduate School in Monterey, California on November 3–4, 1960. The book presents an investigation of the performance of ion rockets employing electron-bombardment ion sources. It also underscores the value of duoplasmatron in ion propulsion. The compilation then looks at the development of a negative ion source. Calibration of mass spectrometer, description of ion source, and the theory of surface ionization are described. The book also discusses experiments on oscillating-electron plasma source; the theory of ion emission from porous media; and the effects of surface structure and adsorption on the ionization efficiency of a surface ionization source. The text also considers a number of experiments, including the space-charge theory for ion beams, circular beam neutralization, and transient and steady state behavior in cesium ion beams. The book is a good source of information for readers wanting to study electrostatic propulsion.
