Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.
This book contains 30-40 quality 2D NMR data sets following an introductory section describing the methodology employed. Many other books describe the methods used, but none offer a large number of problems. Instructors at universities and colleges at the present time are forced to cobble together problems from a wide range of sources. The fragmentary approach to assembling course materials has a negative impact on course continuity and thus adversely impacts student retention. This book will stand as a single source to which instructors and students can go to obtain a comprehensive compendium of NMR problems of varying difficulty. • Presents strategies for assigning resonances to known structures and for deducing structures of unknown organic molecules based on their NMR spectra • Contains 20 known and 20 unknown structure determination problems
The field of nuclear magnetic resonance has experienced a number of spectacular developments during the last decade. Fourier transform methodology revolutionized signal acquisition capabilities. Superconducting magnets enhanced sensitivity and produced considerable improvement in spectral dispersion. In areas of new applicat ions, the life sciences particularly bene fited from these developments and probably saw the largest increase in usage. NMR imaging promises to offer a noninvasive alternative to X rays. High resolution is now achievable with solids, through magic angle spinning and cross polarization, so that the powers of NMR are applicable to previously intractable materials such as polymers, coal, and other geochemicals. The ease of obtaining relaxation times brought an important fourth variable, after the chemical shift, the coupling constant, and the rate constant, to the examination of structural and kinetic problems i~ all fields. Software development, particularly in the area of pulse sequences, created a host of useful tech niques, including difference decoupling and difference nuclear Overhauser effect spectra, multidimensional displays, signal enhancement (INEPT), coupling constant analysis for connectivity (INADEQUATE), and observation of specific structural classes such as only quaternary carbons. Finally, hardware development gave us access to the entire Periodic Table, to the particular advan tage of the inorganic and organometallic chemist. At the NATO Advanced Study Institute at Stirling, Scotland, the participants endeavored to examine all these advances, except imaging, from a multidisciplinary point of view.

Ideal for advanced undergraduate and graduate courses in organic structure analysis, organic structure identification, and organic spectroscopy, it emphasizes real applications--integrating theory as needed--and introduces students to the latest spectroscopic methods. An Instructor's Resource CD-ROM, which includes all of the figures from the text in electronic format and the solutions to all of the exercises and problems from the text (in an editable Word file format), is also available for adopting professors. Please contact your publisher sales representative. FEATURES * Focus on Structure: Opens with structural elements and then considers the characteristics, advantages, and disadvantages of spectroscopic methods. Includes coverage of the steps used in determining a molecular structure, the limitations to organic structure determination by spectroscopic methods, and an "Organic Structure Analyses Gone Bad" table (all unique to this text) * Practical Organization: Presents the most commonly used methods first, beginning with an overview of strategies, followed by the use of NMR, and then moving on to mass spectrometry, infrared, and ultraviolet * Innovative Real-World Problem-Solving Approach: Follows the actual information flow used by chemists to solve molecular structures, as opposed to the standard methods-based approach of other texts * Unique Chapter (12) Featuring 51 Structure-Solving Problems: Each problem emphasizes a different method; the problems increase in difficulty throughout the chapter, successively building on students' knowledge and requiring them to integrate multiple methods to identify molecules. NEW TO THE SECOND EDITION * Coverage of the Latest Instrumental and Computational Advances: Examines the use of modern instruments, data processing, and computer-assisted structure elucidation techniques * Updated and Expanded Treatment of NMR (Chapters 2-5): An extensively revised Chapter 5 discusses multi-pulse 1D and 2D NMR methods, 1D TOCSY and 1D NOESY sequences, and using NOESY and ROESY in determining relative stereochemistry and solution conformation. * Additional Coverage of Mass Spectrometry: A new chapter (7) expands the discussion of mass spectrometry to three chapters (6-8). Topics include cutting-edge MS instrumentation and new information on tandem MS techniques, combining NMR with MS, large-molecule MS, chemo-informatics, and more. * More Exercises and Improved Spectra: The second edition includes 25% more problems than the previous edition (279 total). In addition, many of the spectra, including all of those presented in Chapters 11 and 12, have been reprocessed or reacquired for greater clarity.
Organic Structure Analysis is an ideal text for upper-level undergraduate and first-year graduate courses in organic spectroscopy. It provides students with the background necessary to effectively apply spectroscopic data in establishing features of molecular structure. Unique in its coverage, it is the only text that emphasizes strategies, interpretation, modern techniques, and problem solving. The text's major aim is to show how spectra can be efficiently examined in order to identify a molecule's major structural elements. Organic Structure Analysis adopts a practical approach to the subject which emphasizes building experience; the authors recognize that a combination of problem solving, access to data from models, and understanding the rules of spectral interpretation helps students to build expertise in structure determination from spectra. It outlines elements of theory, but with an emphasis on those directly relevant to spectral interpretation. The text is divided into three major sections: the first section provides extensive coverage of each of the individual methods, the second section illustrates how the strategies of organic structure analysis are actually applied in ten problems whose solutions are provided, and the third section consists of fifty unsolved problems which range from simple monofunctional compounds to complex natural products.

An introduction to modern NMR spectroscopy, Fourth Edition
Author: J.W. Akitt
Publisher: CRC Press
Keeping mathematics to a minimum, this book introduces nuclear properties, nuclear screening, chemical shift, spin-spin coupling, and relaxation. It is one of the few books that provides the student with the physical background to NMR spectroscopy from the point of view of the whole of the periodic table rather than concentrating on the narrow applications of 1H and 13C NMR spectroscopy. Aids to structure determination, such as decoupling, the nuclear Overhauser effect, INEPT, DEPT, and special editing, and two dimensional NMR spectroscopy are discussed in detail with examples, including the complete assignment of the 1H and 13C NMR spectra of D-amygdain. The authors examine the requirements of a modern spectrometer and the effects of pulses and discuss the effects of dynamic processes as a function of temperature or pressure on NMR spectra. The book concludes with chapters on some of the applications of NMR spectroscopy to medical and non-medical imaging techniques and solid state chemistry of both I = F1/2 and I > F1/2 nuclei. Examples and problems, mainly from the recent inorganic/organometallic chemistry literature support the text throughout. Brief answers to all the problems are provided in the text with full answers at the end of the book.
