High Resolution NMR: Theory and Chemical Applications, 3rd Edition

download

High Resolution NMR provides a broad treatment of the principles and theory of nuclear magnetic resonance (NMR) as it is used in the chemical sciences. It is written at an "intermediate" level, with mathematics used to augment, rather than replace, clear verbal descriptions of the phenomena. The book is intended to allow a graduate student, advanced undergraduate, or researcher to understand NMR at a fundamental level, and to see illustrations of the applications of NMR to the determination of the structure of small organic molecules and macromolecules, including proteins. Emphasis is on the study of NMR in liquids, but the treatment also includes high resolution NMR in the solid state and the principles of NMR imaging and localized spectroscopy.

Careful attention is given to developing and interrelating four approaches - steady state energy levels, the rotating vector picture, the density matrix, and the product operator formalism. The presentation is based on the assumption that the reader has an acquaintance with the general principles of quantum mechanics, but no extensive background in quantum theory or proficiency in mathematics is required. Likewise, no previous background in NMR is assumed, since the book begins with a description of the basic physics, together with a brief account of the historical development of the field.
This third edition of High Resolution NMR preserves the "conversational" approach of the previous editions that has been well accepted as a teaching tool. However, more than half the material is new, and the remainder has been revised extensively. Problems are included to reinforce concepts in the book.

Key Features

* Uses mathematics to augment, not replace, verbal explanations
* Written in a clear and conversational style
* Follows the successful format and approach of two previous editions
* Revised and updated extensively--about 70 percent of the text is new
* Includes problems and references to additional reading at the end of each chapter

NMR-MRI, µSR and Mössbauer Spectroscopies in Molecular Magnets

download

In the last years, after the discovery of molecular nanomagnets showing novel quantum effects, a renewed interest for the study of molecular magnetism and multifunctional molecular materials has emerged. These materials have triggered an intense research activity also in view of their possible applicabilities as, for example, as nanosized information storage units and as magnetic nanoparticles for bio-medicine. Several fundamental aspects of the microscopic static and dynamic properties of these molecular materials have been obtained by means of spectroscopies using local probes, as nuclei and muons.

In this book an extensive overview on the results obtained during the last decade and on recent achievements in the study of molecular magnets by means of Nuclear Magnetic Resonance, Muon Spin Rotation, Magnetic Resonance Imaging and Mossbauer techniques is presented. The aim is to introduce the reader to these techniques and to give a general background on their application to molecular spin systems.

NMR Spectroscopy in Pharmaceutical Analysis

For almost a decade, quantitative NMR spectroscopy (qNMR) has been established as valuable tool in drug analysis. In all disciplines, i. e. drug identification, impurity profiling and assay, qNMR can be utilized.
Separation techniques such as high performance liquid chromatography, gas chromatography, super fluid chromatography and capillary electrophoresis techniques, govern the purity evaluation of drugs. However, these techniques are not always able to solve the analytical problems often resulting in insufficient methods. Nevertheless such methods find their way into international pharmacopoeias. Thus, the aim of the book is to describe the possibilities of qNMR in pharmaceutical analysis.
Beside the introduction to the physical fundamentals and techniques the principles of the application in drug analysis are described: quality evaluation of drugs, polymer characterization, natural products and corresponding reference compounds, metabolism, and solid phase NMR spectroscopy for the characterization drug substances, e.g. the water content, polymorphism, and drug formulations, e.g. tablets, powders. This part is accompanied by more special chapters dealing with representative examples. They give more detailed information by means of concrete examples. combines theory, techniques, and concrete applicationsall of which closely resemble the laboratory experience considers international pharmacopoeias, addressing the concern for licensing features the work of academics and researchers, appealing to a broad readership.

Methods for Structure Elucidation by High-Resolution NMR

Nuclear Magnetic Resonance Spectroscopy (NMR) is now widely regarded as having evolved into a subscience. The field has become immensely diverse, ranging from medical use through solid state NMR to liquid state applications, with countless books and scientific journals devoted to these topics. Theoretical as well as experimental advance continues to be rapid, and has in fact accelerated by many novel innovations. This multi-authored book focuses on the latest developments in the rapidly evolving field of high resolution NMR, specifically with a view to applications on the structure elucidation of organic molecules of moderate molecular weight. Conceptually it differs from basic educational texts, hard-core scientific papers and regular review articles in that each chapter may be regarded as the authors' personal account of their special insights and results that crystallised after several years of research into a given topic. The book revolves around several themes and offers a handful of scientific "gems" of various colors, reflecting the great diversity of NMR. It contains 16 loosely connected chapters written by some of today's most accomplished NMR scientists in the world. Each chapter is a unique synthesis of the authors' previous research results in the given field, and thus projects special insights. Much emphasis has been given to the latest developments in NMR, in particular to selective pulses and pulsed field gradients. As a part of the series "Analytical Spectroscopy Library", with subsequent editions coming along this book should provide a platform for future research accounts of similar flavor. The material is presented in a mostly non-mathematical fashion, and is intended mainly for chemists, application NMR scientists and students with already some background in NMR. Some of the chapters slightly overlap in the discussed topics, which is particularly exciting in terms of gaining insight into the same area from different angles.

Structure Elucidation by NMR in Organic Chemistry
Publisher: Wiley | 3 edition (December 3, 2002) | ISBN: 0470850078 | Pages: 270 | PDF | 8.7 MB

This text provides the graduate student with a systematic guide to unravelling structural information from the NMR spectra of unknown synthetic and natural compounds. A brief introduction gives an overview of the basic principles and elementary instrumental methods of NMR. This is followed by instructional strategy and tactical advice on how to translate spectra into meaningful structural information. The book provides the student with 55 sets of spectra of graduated complexity. These are designed to challenge the student's problem-solving abilities by the introduction of new concepts with each group of problems, followed by possible solutions and full explanations. A formula index of solutions is provided at the end of the text. This third edition, following on from the second (a reprint of the first edition with corrections), presents significant new material. Thus, actual methods of two-dimensional NMR such as some inverse techniques of heteronuclear shift correlation, as well as the detection of proton-proton connectivities and nuclear Overhauser effects are included. To demonstrate the applications of these methods, new problems have replaced those of previous editions.
