Carbon NMR is a valuable tool for the study of organic materials. The NMR parameters are directly correlated with the structural properties of the various carbon sites. Modern spectrometers make feasible carbon spectroscopy on samples containing 13 C at natural abundance.

With the development of modern NMR technology, a host of techniques. @article{osti_, title = {Carbon NMR spectroscopy}, author = {Kalinowski, H O and Berger, S and Braun, S}, abstractNote = {This eight-chapter book was originally published in German in Although a few more recent Carbon-13 Nmr Spectral Data book were added during translation, the majority are from the s.

Appendices include answers to problems presented in the text, selected reading, a list of. The book then considers the safety aspects of NMR spectroscopy, reviewing NMR software for spectral prediction and data handling and concludes with a set of worked Q&As.

“Essential Practical NMR for Organic Chemistry” is a small volume aimed at the bench chemist, written by two chemists from GSK. The book covers the fundamentals of sample preparation, 1H, and 13C NMR, with an emphasis on the practical aspects rather than explaining the nature of the pulse sequence by: Nearly twenty years later, the introduction of 13 C NMR spectroscopy early in the course is technically possible since many undergraduate institutions now have access to an NMR instrument with 13 C capability or can download spectral data from various internet databases such as the Structural Database for Organic Compounds (SDBS).
