Understanding Mass Spectra : A Basic Approach

Understanding Mass Spectra: A Basic Approach, Second Edition combines coverage of the principles underlying mass spectral analysis with clear guidelines on how to apply them in a laboratory setting. Completely revised from the first edition, an updated and unified approach to mass spectral interpretation emphasizes the application of basic principles from undergraduate organic, analytical, and physical chemistry courses. A detailed overview of theory and instrumentation, this useful guide contains step-by-step descriptions of interpretative strategies and convenient lists and tables detailing the information needed to solve unknowns. Other features include real-world case studies and examples, skill-building problems with clearly explained answers, and easy-to-follow explanations of the important mathematical derivations.Content: Chapter 1 Instrumentation (pages 1–55): Chapter 2 Elemental Composition from Peak Intensities (pages 56–98): Chapter 3 Ionization, Fragmentation, and Electron Accounting (pages 99–120): Chapter 4 Neutral Losses and Ion Series (pages 121–149): Chapter 5 A Rational Approach to Mass Spectral Problem Solving (pages 150–163): Chapter 6 ??Cleavage and Related Fragmentations (pages 164–206): Chapter 7 Important Mass Spectral Rearrangements (pages 207–237): Chapter 8 Rationalizing Mass Spectral Fragmentations (pages 238–256): Chapter 9 Structure Determination in Complex Molecules Using Mass Spectrometry (pages 257–286): Chapter 10 Answers to Problems (pages 287–352): Understanding Mass Spectra: A Basic Approach, Second Edition Presents The Introductory-level Student With The Fundamental Concepts Of Mass Spectrometry, Providing A Useful Foundation For Solving Basic Problems In A Laboratory Setting.

Includes Bibliographical References And Index. Drawing upon his many years as a forensic chemist and an instructor of mass spectral interpretation, R. Martin Smith combines coverage of the principles underlying mass spectral analysis with clear guidelines on how to apply them in a laboratory setting. Writing from the perspective of a professional analytical chemist - but at a level accessible to chemistry undergraduates - he approaches the subject within the context of several key unifying concepts from organic and physical chemistry, including the roles of molecular orbitals in the ionization process and "electron pushing" for rationalizing reaction mechanisms. Discussions of instrumentation are the result of a collaboration with Kenneth L. Busch, a recognized expert in mass spectrometry, who served as technical editor for the book.
