Download or read book Carbon 13 NMR of Flavonoids written by P.K. Agrawal and published by Elsevier. This book was released on 2013-10-22 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Carbon 13 NMR Shift Assignments of Amines and Alkaloids written by M. Shamma and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to gather under one cover most of the data presently available on the carbon-13 nuclear magnetic resonance (cmr) spectra of alkaloids. The term "alkaloids" is used here in a very broad sense to include synthetic analogues of the natural products. Simple model amines are also incorporated since these often supply the basic information required in the assignment of chemical shifts for the more complex compounds. The literature on alkaloid cmr spectroscopy has been covered through 1977, but the collec tion of compounds presented here is illustrative rather than exhaustive. The papers included in the reference list afford further information not only on the cmr assignments of the particular compounds provided here, but also incorporate data on additional related structures. Only a few dimeric indole alkaloids are included since to a large extent their cmr spectra can be corre lated directly with those of their monomeric analogues. The present volume is thus a representative empirical compendium of cmr assignments focusing upon alkaloids and model amines, and is intended to aid cmr research in heterocyclic and alkaloid chemistry. The compounds and data presented in this book are classified and organized according to structural similarity. The purpose of such a presenta tion is to demonstrate the common cmr characteristics of a given structural type, while also facilitating an empirical evaluation of the cmr spectral changes specifically reSUlting from relatively minor variations in oxidation level, substitution, or stereochemistry.

Download or read book Tables of Spectral Data for Structure Determination of Organic Compounds written by Ernö Pretsch and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although numerical data are, in principle, universal, the compilations presented in this book are extensively annotated and interleaved with text. This translation of the second German edition has been prepared to facilitate the use of this work, with all its valuable detail, by the large community of English-speaking scientists. Translation has also provided an opportunity to correct and revise the text, and to update the nomenclature. Fortunately, spectroscopic data and their relationship with structure do not change much with time so one can predict that this book will, for a long period of time, continue to be very useful to organic chemists involved in the identification of organic compounds or the elucidation of their structure. Klaus Biemann Cambridge, MA, April 1983 Preface to the First German Edition Making use of the information provided by various spectroscopic tech niques has become a matter of routine for the analytically oriented organic chemist. Those who have graduated recently received extensive training in these techniques as part of the curriculum while their older colleagues learned to use these methods by necessity. One can, therefore, assume that chemists are well versed in the proper choice of the methods suitable for the solution of a particular problem and to translate the experimental data into structural information.
Download or read book High resolution NMR Techniques in Organic Chemistry written by T. Claridge and published by Elsevier. This book was released on 1999-12-24 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the initial observation of proton magnetic resonance in water and in paraffin, the discipline of nuclear magnetic resonance has seen unparalleled growth as an analytical method. Modern NMR spectroscopy is a highly developed, yet still evolving, subject which finds application in chemistry, biology, medicine, materials science and geology. In this book, emphasis is on the more recently developed methods of solution-state NMR applicable to chemical research, which are chosen for their wide applicability and robustness. These have, in many cases, already become established techniques in NMR laboratories, in both academic and industrial establishments. A considerable amount of information and guidance is given on the implementation and execution of the techniques described in this book.

Download or read book Phosphorus 31 NMR Spectroscopy written by Olaf Kühl and published by Springer Science & Business Media. This book was released on 2008-08-22 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Magnetic Resonance is a powerful tool, especially for the identification of 1 13 hitherto unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every synthetically working Organic Chemist. Con- quently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc. , are well understood, and specialty methods developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelors degree courses, with advanced methods integrated into masters degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectr- copy within the chemical community, it is remarkable that heteronuclear NMR is still looked upon as something of a curiosity. Admittedly, most organic compounds contain only nitrogen, oxygen, and sulfur atoms, as well as the obligatory hydrogen and carbon atoms, elements that have an unfavourable isotope distribution when it comes to NMR spectroscopy. Each of these three elements has a dominant isotope: 14 16 32 16 32 N (99. 63% natural abundance), O (99. 76%), and S (95. 02%), with O, S, and 34 14 S (4. 21%) NMR silent. N has a nuclear moment I = 1 and a sizeable quadrupolar moment that makes the NMR signals usually very broad and dif cult to analyse.
