Download or read book Interpr tation des spectres de masse en couplage GC MS cours et exerices corrig s written by BOUCHONNET Stéphane and published by Lavoisier. 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.

This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades the organic chemist has become in creasingly used to take advantage of more and more complex instrumenta tion and physical measurements in lieu of laborious, time-consuming and often ambiguous chemical transformations. Mass spectrometry is perhaps the most recent, most complex and most expensive addition to this field. In view of the astonishingly quick acceptance of nuclear magnetic reso nance by the organic chemist it is, in retrospect, surprising that he has neglected mass spectrometry for such a long time. This can be explained, in part, by the complexity of the instrumentation and some technical shortcomings of the earlier commercially available instruments but, to an even greater extent, it reflects also the prejudices against a technique that was originally mainly used for quantitative gas analysis. The usefulness of mass spectrometry as a qualitative technique in organic chemistry rather than a tool for quantitative analysis was more and more recognized towards the end of the last decade. A rather spectacular development followed during the intervening few years to the point that now any reasonably well equipped modern organic laboratory is supplied with, or at least has access to, one or more mass spectrometers suitable for work on organic compounds. Within the realm of organic chemistry the technique has become much more important, if not indispensable, for the natural products chemist while its application to synthetic problems is much less pro nounced.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
