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.

Extensively revised and updated, this new edition, as in previous editions, emphasizes the point that the most important part of learning how to interpret unknown mass spectra is to practice interpreting mass spectra.

Die Massenspektrometrie ist eine der wenigen Techniken, mit denen man organische Verbindungen eindeutig identifizieren kann. Dieses Buch behandelt die Interpretation von Massenspektren organischer Verbindungen, und zwar auf einem für Studienanfänger und Fortgeschrittene geeigneten Niveau. Die verschiedenen organischen Verbindungen werden in einzelnen Kapiteln besprochen, wobei der Schwerpunkt auf einem verbindungsspezifischen Ansatz zur Interpretation von Massenspektren liegt. Einfach und verständlich geschrieben mit mehr als 120 repräsentativen Spektren, ist dieses Werk speziell für Studierende im 2. und 3. Studienjahr sowie für Neulinge auf diesem Gebiet gedacht.

Although there are a number of books in this field, most of them lack an introduction of comprehensive analysis of MS and IR spectra, and others do not provide up-to-date information like tandem MS. This book fills the gap. The merit of this book is that the author will not only introduce knowledge for analyzing nuclear magnetic resonance spectra including 1H spectra (Chapter 1), 13C spectra (Chapter 2) and 2D NMR spectra (Chapter 3), he also arms readers systemically with knowledge of Mass spectra (including EI MS spectra and MS spectra by using soft ionizations) (Chapter 4) and IR spectra (Chapter 5). In each chapter the author presents very practical application skills by providing various challenging examples. The last chapter (Chapter 6) provides the strategy, skills and methods on how to identify an unknown compound through a combination of spectra. Based on nearly 40 years researching and teaching experience, the author also proposes some original and creative ideas, which are very practical for spectral interpretation.

A unique advanced textbook on spectroscopy. This interactive tutorial presents text, software and data in a state-of-the-art introduction to the interpretation of 13C- and 1H-nuclear magnetic resonance, infrared, mass and UV/VIS spectra. Designed as a hands-on guide, the newcomer or student learns not only by reading but by experimenting, using the powerful software tools and data provided on the accompanying CD-ROM. The software, based on the outstanding SpecTool product, enables you to learn how to interpret molecular spectra correctly, rapidly and easily. Moreover, you can check your progress by working through the examples embedded in this self-study course that demonstrate how to identify an organic compound and to elucidate its structure. All the material and software presented are the essence of the two authors? longstanding teaching experience.

Although numerical data are, in principle, universal, the compilations presented in this book are extensively annotated and interleaved with text. This translation of the second German edition has been prepared to facilitate the use of this work, with all its valuable detail, by the large community of English-speaking scientists. Translation has also provided an opportunity to correct and revise the text, and to update the nomenclature. Fortunately, spectroscopic data and their relationship with structure do not change much with time so one can predict that this book will, for a long period of time, continue to be very useful to organic chemists involved in the identification of organic compounds or the elucidation of their structure. Klaus Biemann Cambridge, MA, April 1983 Preface to the First German Edition Making use of the information provided by various spectroscopic tech niques has become a matter of routine for the analytically oriented organic chemist. Those who have graduated recently received extensive training in these techniques as part of the curriculum while their older colleagues learned to use these methods by necessity. One can, therefore, assume that chemists are well versed in the proper choice of the methods suitable for the solution of a particular problem and to translate the experimental data into structural information.
