Mass spectrometry has played an integral part in the study of organic molecular structures for more than 50 years, offering significant information from small amounts of sample. The mass spectrum produced by electron impact ionization presents a pattern of peaks that can often give definitive structural information about an unknown compound. Introductory Mass Spectrometry, Second Edition guides readers in the understanding and recognition of those patterns, discussing mass spectra in terms that are familiar to chemists. It provides a basis for chemists to interpret mass spectra to solve particular structural problems. The Second Edition has been updated with modern techniques and data handling. Beginning with an introduction to the principles and instrumentation, it then sequentially explains the processes that occur in the mass spectrometer following ionization. The book is unique in the large number of mass spectra presented and provides examples of mass spectra from a wide variety of organic chemicals, concentrating on the relationships between fragmentation patterns, common chemical reactions, and chemical structures. The book also discusses mass spectra obtained with softer ionization techniques, which provide definitive information regarding molecular weights. The text describes mass spectra produced by electron ionization, discussing how the spectral peak pattern relates to molecular structure. It details the use of high-resolution and accurate mass measurement to determine elemental composition of ions in order to identify unknown substances. The book also introduces some of the recent techniques that can be employed to extend the usefulness of mass spectrometry to high molecular weight substances and more polar substances. It includes examples and problems representing a cross section of organic chemistry to help readers integrate the principles presented.

An updated and unified approach to mass spectral interpretation, emphasizing the application of basic principles Electron ionization (EI) mass spectrometry-an analytical tool used by chemists to identify and quantify compounds in a complex mixture-remains an essential technique for measuring low-molecular weight compounds such as drugs, flavor and odor components, pesticides, and petroleum products. The interpretation of EI mass spectra also remains an important skill because attempts to identify compounds using computer databases do not always yield useful results. 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. Completely revised, the Second Edition includes: A detailed overview of theory and instrumentation Step-by-step descriptions of interpretative strategies Many fascinating real-world case studies and examples Additional skill-building problems with clearly explained answers Easy-to-follow explanations of all important mathematical derivations Convenient lists and tables of information needed to identify unknowns Additional suggested readings Containing problems and examples with a wide range of complexity, Understanding Mass Spectra emphasizes simple, practical treatments of topics such as fragmentation types and underlying mathematical relationships. Mastering these treatments allows for a solid grounding in basic principles and encourages advanced investigation. With this emphasis on comprehension, Understanding Mass Spectra, Second Edition provides a vital introduction to the field for upper-level undergraduates and beginning graduates, as well as a valuable resource for professional chemists working in analytical laboratories.
