This book was released on 2012-09-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: C’est avec une réelle volonté didactique que cet ouvrage aborde l’interprétation des spectres de masse pour confirmer ou élucider des structures chimiques. Les publications scientifiques dédiées à la spectrométrie de masse sont souvent complexes et présentent une approche très théorique, souvent difficile à comprendre et à mettre en pratique. Ce livre se fait fort, grâce à sa simplicité et à sa démarche ancrée dans la pratique, d’offrir aux débutants comme aux spécialistes du domaine, les clés de cette technique. Un premier chapitre présente des rappels de chimie organique nécessaires à une bonne compréhension des réactions impliquées. Dans un deuxième chapitre, les mécanismes de formation et de dissociation des ions sont détaillés : ruptures simples et réarrangements, fragmentations secondaires, etc. Ces mécanismes sont illustrés de nombreux exemples concrets. La seconde partie de cet ouvrage propose une cinquantaine d'exercices corrigés permettant d'acquérir maîtrise et autonomie. À la fois manuel universitaire et guide pratique quotidien, L’interprétation des spectres de masse en couplage GC-MS constitue une référence pour tous les utilisateurs de couplage GC-MS tels que les ingénieurs, techniciens, chercheurs, étudiants, etc., débutants ou confirmés, désireux d'interpréter judicieusement leurs spectres de masse. Outre l'élucidation structurale, la compréhension des mécanismes qui régissent l'interprétation des spectres permet l'amélioration des méthodes analytiques et la fiabilisation des résultats.

Download or read book Mass Spectrometry of Organic Ions written by F.W. McLafferty and published by Elsevier. This book was released on 2012-12-02 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass Spectrometry of Organic Ions covers the underlying theories and major applications of mass spectrometry. This 13-chapter book starts with a survey of the mechanisms by which organic ions can decompose and rearrange, as well as the generalized concept in terms of physical-organic chemistry. The discussion then shifts to the advantages and potential of mass spectrometry in structure determination by the elucidation of the empirical formulas of organic ions. Considerable chapters are devoted to the detailed correlations and mechanisms of the mass spectra of long-chain esters, alkylbenzenes, a variety of natural products, aliphatic compounds, and terpenes. The remaining chapters demonstrate the illustrative power of mass spectrometry in structure of petroleum, which is composed of hydrocarbon mixture. This book will be of great benefit to organic and analytical chemists, scientists, and students.

Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Download or read book Interpretation of Mass Spectra of Organic Compounds written by Mynard Hamming and published by Elsevier. This book was released on 2012-12-02 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-03-09 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: While modem techniques of nuclear magnetic resonance and mass spectrometry changed the ways of data acquisition and greatly extended the capabilities of these methods, the basic parameters, such as chemical shifts, coupling constants, and fragmentation pathways remain the same. This explains the ongoing success of the earlier editions of this book. However, since the amount of available data has considerably increased over the years, we decided to prepare an entirely new manuscript. It follows the same basic concepts, i. e. , it provides a representative, albeit limited set of reference data for the interpretation of 13C NMR, 1 H NMR, IR, mass, and UV Nis spectra. On the other hand, the book has undergone a number of changes. The amount of reference data has been doubled at least (especially for MS and IR) and the order and selection of data for the various spectroscopic methods is now arranged strictly in the same way. In addition, the the enclosed compact disc contains programs for estimating NMR chemical shifts and generating isomers based on structural information. Unfortunately, our teachers and colleagues, Prof. Wilhelm Simon and Prof. Thomas Clerc are no longer among us, and Prof. Joseph Seibl has retired years ago. Their contributions to developing the concept and the earlier editions of this work cannot be overemphasized. We also thank numerous colleagues who helped us in many different ways to complete the manuscript. Weare particularly indebted to Dr.
