Nuclear magnetic resonance (NMR) is an analytical tool used by chemists and physicists to study the structure and dynamics of molecules. In recent years, no other technique has gained such significance as NMR spectroscopy. It is used in all branches of science in which precise structural determination is required and in which the nature of interactions and reactions in solution is being studied. Annual Reports on NMR Spectroscopy has established itself as a premier means for the specialist and non-specialist alike to become familiar with new techniques and applications of NMR spectroscopy.

This work-book will guide you safely, in step-by-step descriptions, through every detail of the NMR experiments within, beginning with 1D routine experiments and ending with a series of advanced 3D experiments on a protein: ? Which experiment can best yield the desired information? ? How must the chosen experiment be performed? ? How does one read the required information from the spectrum? ? How does this particular pulse sequence work? ? Which other experiments give similar information? This third edition of the book, following its two highly successful predecessors, has been revised and expanded to 206 experiments. They are organized in 15 chapters, covering test procedures and routine spectra, variable temperature measurements, the use of auxiliary reagents, 1D multipulse experiments, spectra of heteronuclides, and the application of selective pulses. The second and third dimensions are introduced using pulsed field gradients, and experiments on solid state materials are described. A key part describes 3D experiments on the protein ubiquitin with 76 amino acids. What is new in this third edition? 1. 24 new experiments have been inserted into the 14 chapters that were in the 2nd edition, e.g., alpha/beta-SELINCOR-TOCSY, WET, DOSY, ct-COSY, HMSC, HSQC with adiabatic pulses, HETLOC. J-resolved HMBC, (1,1)- and (1,n)-ADEQUATE, STD, REDOR, and HR-MAS. 2. 20 new protein NMR experiments have been specially devised and are collected in the newly added Chapter 15, ProteinNMR, for which one needs a special model sample: fully 13C- and 15N-labeled human ubiquitin. Techniques used include the constant time principle, the PEP method, filters, gradient selection, and the echo/anti-echo procedure. The guide has been written by experts in this field, following the principle of learning by doing: all the experiments have been specially performed for this book, exactly as described and shown in the spectra that are reproduced. Being a reference source and work-book for the NMR laboratory as well as a textbook, it is a must for every scientist working with NMR, as well as for students preparing for their laboratory courses

A blend of theory and practical advice, Modern NMR Techniques for Synthetic Chemistry illustrates how NMR spectroscopy can be used to determine the abundance, size, shape, and function of organic molecules. It provides you with a description the NMR technique used (more pictorial than mathematical), indicating the most common pulse sequences, some practical information as appropriate, followed by illustrative examples. This format is followed for each chapter so you can skip the more theoretical details if the practical aspects are what interest you. Following a discussion of basic parameters, the book describes the utility of NMR in detecting and quantifying dynamic processes, with particular emphasis on the usefulness of saturation-transfer (STD) techniques. It details pulsed–field gradient approaches to diffusion measurement, diffusion models, and approaches to ‘inorganic’ nuclei detection, important as many synthetic pathways to new organics involve heavier elements. The text concludes with coverage of applications of NMR to the analysis of complex mixtures, natural products, carbohydrates, and nucleic acids—all areas of activity for researchers working at the chemistry-life sciences interface. The book’s unique format provides some theoretical insight into the NMR technique used, indicating the most common pulse sequences. The book draws upon several NMR methods that are resurging or currently hot in the field and indicates the specific pulse sequence used by various spectrometer manufacturers for each technique. It examines the analysis of complex mixtures, a feature not found in most books on this topic.

During the last two decades, the use of NMR spectroscopy for the characterization and analysis of food materials has flourished, and this trend continues to increase today. Currently, there exists no book that fulfils specifically the needs of food scientists that are interested in adding or expanding the use of NMR spectroscopy in their arsenal of food analysis techniques. Current books and monographs are rather addressed to experienced researchers in food analysis providing new information in the field. This book, written by acknowledged experts in the field, fills the gap by offering a day to day NMR guide for the food scientist, affording not only the basic theoretical aspects of NMR spectroscopy, but also practical information on sample preparation, experimental conditions and data analysis. Current developments in the field covered in this book are the availability of solid state NMR experiments such as CP/MAS and more importantly HR-MAS NMR for the analysis of semisolid foods, and the increasing use of chemometrics to analyze NMR data in food metabonomics. Moreover, this book contains an up to date discussion of MRI in food analysis including topics such as food processing and natural changes in food such as ripening. The book is a compact and complete source of information for food scientists who wish to apply methodologies based on NMR spectroscopy in food analysis. It contains information so far scattered in the primary literature, in NMR treatises and food analysis books, in a concise format that makes it appealing to food scientists who have no or minimal experience in magnetic resonance techniques. The inclusion of practical information about NMR instrumentation, experiment setup, acquisition and spectral analysis for the study of different food categories make this book a hands-on manual for food scientists wishing to implement novel NMR spectroscopy-based analytical techniques in their field.

Plants and plant-derived compounds and drugs are becoming moreand more popular with increasing numbers of scientists researchingplant analysis. The quality control of herbal drugs is alsobecoming essential to avoid severe health problems, and in thefuture many more new drugs will be developed from plantsources. This three-volume Handbook, featuring 47 detailed review articles,is unique as it deals with chemical and biological methodologiesfor plant analysis. It presents the most important and mostaccurate methods which are available for plant analysis. This comprehensive work is divided into six sections asfollows: Sample preparation and identification – discussingplant selection and collection, followed by extraction and samplepreparation methodologies. Extraction and sample preparation methodologies Instrumentation for chemical analysis - severalinstrumentations for chemical plant analysis are presented with anemphasis on hyphenated techniques, e.g. the coupling between HPLCand mass spectroscometry, and HPLC with NMR. Strategies for selective classes of compounds –coverage of the most interesting classes of compounds such aspolysaccharides, saponins, cardiotonic glycosides, alkaloids,terpenoids, lipids, volatile compounds and polyphenols (flavonoids, xanthones, coumarins, naphthoquinones, anthraquinones,proanthocyanidins, etc.). Biological Analysis - includes phenotyping, DNA barcodingtechniques, transcriptome analysis , microarray, metabolomics andproteomics. Drugs from Plants – covers the screening of plantextracts and strategies for the quick discovery of novelbioactive natural products. Safety assessment of herbal drugs ishighly dependent on outstanding chromatographic and spectroscopicmethods which are also featured here.
