Book Description
Newcomers to the field will find this book indispensable. Experts, such as organic mass spectrometrists in the chemical, pharmaceutical, and petrochemical industries, will find it a valuable time-saver in interpreting the spectrum of an unfamiliar compound when information is lacking on the history of the sample. This volume is an invaluable resource for interpreting the copious spectral data generated in gas chromatography and mass spectrometry investigations. Comprehensive tables show the most probable assignments for peaks in electron ionization mass spectra of organic compounds. This expanded edition lists more than 3000 structures corresponding to 1500 elemental compositions, several times the number in the first edition of this book published in 1963.

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
Edited by world-famous pioneers in chemoinformatics, this is a clearly structured and applications-oriented approach to the topic, providing up-to-date and focused information on the wide range of applications in this exciting field. The authors explain methods and software tools, such that the reader will not only learn the basics but also how to use the different software packages available. Experts describe applications in such different fields as structure-spectra correlations, virtual screening, prediction of active sites, library design, the prediction of the properties of chemicals, the development of new cosmetics products, quality control in food, the design of new materials with improved properties, toxicity modeling, assessment of the risk of chemicals, and the control of chemical processes. The book is aimed at advanced students as well as lectures but also at scientists that want to learn how chemoinformatics could assist them in solving their daily scientific tasks. Together with the corresponding textbook Chemoinformatics - Basic Concepts and Methods (ISBN 9783527331093) on the fundamentals of chemoinformatics readers will have a comprehensive overview of the field.

Book Description
A personal mass spectra database was built for 1,813 hydrocarbons, containing the m/z of the base peaks as well as the 10-13 m/z of the characteristic peaks, about 10% higher in the increasing order of ionic strength and expressing at most only the relative sizes in the order of these arrangements. There appears to be a close relationship between the peaks appearing in the mass spectra and the chemical structure of the molecules, as well as a close relationship between the ion peaks and the molecular structure. This report examines the correlation between the structural data held mainly by the molecular formulae and the base peaks, as well as the other characteristic peaks.
