This is a methods-oriented book, which contains enormous amounts of information on 31P NMR, in a concise and well-edited format. It is an invaluable resource for every NMR spectroscopist. This book consists of 33 chapters, which together 'constitute a compendium that will be of optimal utility to the majority of 31P NMR spectroscopy users as well as to those perhaps not as familiar with the technique but curious about potential applications in their own research.' (From the editors' preface) There have been a number of new developments in NMR techniques in the 6 years since Verkade and Quin edited the first, successful book on 31P NMR. This new book does not supersede the previous book; it offers a wide cross-section of recent research. Compard to the first, basic, grounding volume, this book presents more results (it is more applied); it directly reflects a more mature science. Arguably, VCH has published the best NMR books in recent years (Neuhaus/Williamson, Croasmun/Carlson, etc.). This new addition to VCH's NMR list ensures the continued visibility and excellence of VCH in this field.

Filling the gap for an up-to-date reference that presents the field of organophosphorus chemistry in a comprehensive and clearly structured way, this one-stop source covers the chemistry, properties, and applications from life science and medicine. Divided into two parts, the first presents the chemistry of various phosphorus-containing compounds and their synthesis, including ylides, acids, and heterocycles. The second part then goes on to look at applications in life science and bioorganic chemistry. Last but not least, such important practical aspects as 31P-NMR and protecting strategies for these compounds are presented. For organic, bioinorganic, and medicinal chemists, as well as those working on organometallics, and for materials scientists. The book, a contributed work, features a team of renowned scientists from around the world whose expertise spans the many aspects of modern organophosphorus chemistry.

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.

Phosphorous-31 NMR: Principles and Applications focuses on the evolution of phosphorus-31 nuclear magnetic resonance (NMR) as a widely applied spectroscopic probe of the structure and dynamics of phosphorus-containing compounds. The selection first offers information on the principles and empirical observations of phosphorus-31 chemical shifts and the principles and applications of phosphorus-31 spin-spin coupling constants. Discussions focus on introduction and basic principles, directly bonded phosphorus coupling constants, and two-bond and three-bond coupling constants. The text then ponders on phosphorus-31 NMR of enzyme complexes and paramagnetic probes of enzyme complexes with phosphorus-containing compounds. The manuscript elaborates on the use of chiral thiophosphates and the stereochemistry of enzymatic phosphoryl transfer and DNA and RNA conformations. Topics include helix-coil transitions, sequence dependence of double-stranded DNA conformations, dynamic behavior of RNA and DNA, biological and genetic significance, and stereochemical problems studied with chiral thiophosphates. The conformation and dynamics of nucleic acids and phosphoproteins, relaxation behavior of nucleic acids, and theory and applications of solid-state phosphorus-31 NMR to nucleic acids are also discussed. The selection is a valuable reference for readers interested in the principles and applications of phosphorus-31 nuclear magnetic resonance.

To fully utilize Nuclear Magnetic Resonance (NMR) spectroscopy, a comprehensive and well-organized compilation of NMR data is necessary. While compilations have been available for other important NMR nuclei, such as carbon and fluorine, no comprehensive collection of data has been prepared for phosphorus-until now. The CRC Handbook of Phosphorus-31 Nuclear Magnetic Resonance Data provides a collection of 31P NMR chemical shifts for nearly 20,000 organic and inorganic phosphorus compounds. Each class of phosphorus compound is discussed. Bond types, stereochemistry (with the exception of metal complexes), media, important coupling constants, and data sources are included. The information is systematically organized according to coordination state, the atoms bound to phosphorus, and their connectivities. A comprehensive series of bar charts is also included to allow structure types to be assigned to chemical shift data. This handbook is an invaluable resource for all scientists working with phosphorus compounds, including chemists, biochemists, medical researchers, and pharmaceutical chemists.

Unter Zirkulardichroismus (CD) versteht man die spezifisch unterschiedliche Absorption von links- und rechtszirkular polarisiertem Licht durch bestimmte Moleküle. CD-Effekte lassen sich in Abhängigkeit von der Wellenlänge messen und spektroskopisch auswerten; sie geben beispielsweise Auskunft über die Konformation organischer Verbindungen. Dieses Buch richtet sich an den organischen Chemiker, der mit den Grundprinzipien der Stereochemie vertraut ist, und erläutert die Anwendung der CD-Spektroskopie zur Konformationsanalyse ausführlich und verständlich.

An up-to-date compilation of the theoretical background and practical procedures involved in lignin characterization. Whenever possible, the procedures are presented in sufficient detail to enable the reader to perform the analysis solely by following the step-by-step description. The advantages and limitations of individual methods are discussed and, more importantly, illustrated by typical analytical data in comparison to results obtained from other methods. This handbook serves the need of researchers and other professionals in academia, the pulp and paper industry as well as allied industries. It is equally useful for those with no previous experience in lignin or lignocellulosics.
