Carbon-13 NMR Spectroscopy focuses on the potential of 13C techniques and the practical difficulties associated with the detection of 13C NMR absorption. This monograph includes a descriptive presentation of 13C shielding results that has been adopted with emphasis on the structural and stereochemical aspects. Organized into four parts encompassing 11 chapters, this book starts with an overview of the characteristics of the NMR signals derived from compounds containing 13C nuclei in natural abundance that are inherently much weaker than those exhibited by protons. This monograph then compares the primary characteristics of 13C NMR with the more familiar proton methods. Other chapters consider the 13C spectra of pyridine, pyridazine, pyrimidine, pyrazine, s-triazine, and s-tetrazine. The final chapter deals with the effects of solute–solvent interactions on the shieldings of other nuclei. This monograph is intended for organic chemists, graduate students, and researchers in various branches of chemistry with an interest in 13C NMR methods as another approach to chemical problems.

E. Breitmaier, W. Voelter Carbon-13 NMR Spectroscopy High-Resolution Methods and Applications in Organic Chemistry and Biochemistry Third, completely revised edition New techniques and increased use of computers have led to rapid development in 13C NMR spectroscopy with enhanced instrumental sensitivity and improved quality of the spectra. This necessitated a complete revision when the third edition of this successful monograph was prepared. The new methods described include those for multiplicity analysis and two-dimensional homo- or hetero-nuclear shift correlations. As in the second edition, the authors survey the large number of 13C NMR applications to organic molecules and natural products in a representative and systematic rather than an exhaustive way. New sections about coupling constants, organophosphorus and organometallic compounds as well as synthetic polymers have been added. The scope remains limited to high-resolution methods and molecular systems.

This detailed treatise is written for chemists who are not NMR spectroscopists but who wish to use carbon-13 NMR spectroscopy. It shows why measurement of carbon-13 NMR is needed and explains how the method can - or should - be used for rapid characterization of flavonoids, one of the most diverse and widespread groups of natural constituents. The first part of the book presents background information and discussion of the essential aspects of flavonoids and carbon-13 NMR spectroscopy and demonstrates its significant role in the revision of several earlier established chemical structures. It discusses various one- and two-dimensional NMR spectroscopic techniques and other relevant experimental methodologies for the interpretation of spectral details which enable individual resonance lines to be associated with the appropriate carbons in a molecule. The second part provides a comprehensive coverage of the carbon-13 chemical shifts of various classes and subclasses of flavonoids. It also illustrates how to utilize carbon-13 data to gain information for the determination of the nature, number and site of any substituent in flavonoids. Vital information for the differential and complete structure elucidation of the various classes of flavonoids by carbon-13 NMR shielding data is described in-depth in the third part of the book. The book will be welcomed by all those working in natural product chemistry who will appreciate the non-mathematical approach and the fact that such a wealth of theoretical and practical information has been assembled in a single volume.

In addition to capillary gas chromatography and GC-MS, carbon-13 NMR spectroscopy provides an alternative method for essential oils analysis. The excellent visual spacing of the signals enables oil samples to be analyzed without preliminary separation of their components. Also, information relating to the molecular structure of the oil constituents can be ascertained from the measured chemical shifts. This second edition clearly demonstrates the power of the technique in the characterization of essential oils, based on 60 sample oils chosen for their industrial importance together with the 188 carbon-13 NMR spectra of significant components. Supporting data are presented using capillary gas chromatography. Key features of the Second Edition: * 18 new essential oils are included, five oils are replaced and five oils with less or little importance are deleted * Revision of numerous analyses taken over from the 1st edition * Capillary gas chromatograms of 60 commercially important essential oils * Qualitative and quantitative analytical results of those essential oils * Carbon-13 NMR analyses of those essential oils without separation of their components * Carbon-13 NMR spectra of 188 most important oil constituents are given (67 are new in the 2nd edition) This collection of 13C NMR and GC data is aimed at essential oils and natural products chemists, NMR research groups, university departments of chemistry, pharmacy, botany, and food science, as well as those working in the essential oils, perfumes, flavours and food technology industries.

Through numerous conversations with other synthetic chemists it became apparent that the great power of carbon nuclear magnetic resonance was being significantly underutilized. In our own work we have found that 13C spectroscopy is a more powerful tool than IH NMR spectroscopy, especially for probing subtle stereochemical questions in complicated systems. This is especially true in five membered ring compounds where IH NMR is at a particular disadvantage. The two techniques can be used independently to solve the same question-that of stereochemistry - but they do so in different ways. Advantage can be taken in IH NMR of a relatively consistent relationship between stereochemical orientation and coupling constants between vicinal protons, while in 13C NMR it is the correlation between spatial relationships of non-hydrogen, y substituents and their effect on chemical shift that can be used to assign stereochemistry. It was also clear that the use of 13C NMR required a different approach to problem solving than that typically used with IH NMR. While the latter technique could be employed with a very general approach (e.g., the Karplus equation), 13C NMR would, at least for the immediate future, require a relatively extensive set of model systems from which the consequences of stereochemical changes could be derived for any given carbon framework.
