ABC's of FT-NMR by John D. Roberts Pdf

The primary purpose of this book is to help you understand what is going on in Fourier Transform (FT) Nuclear Magnetic Resonance (NMR) spectroscopy. Modern life is now very largely life with 'black boxes' that carry warning labels: 'No user-serviceable parts inside.' Many find black boxes to be quite acceptable, at least as long as they work. But how willing should we be to accept black-box analyses without some understanding of how those analyses were obtained? NMR spectrometers are like 'black boxes' in that they offer many standardised procedures, but it can be dangerous to the quality of your data if you rely slavishly on such procedures without understanding how and why the proper parameter choices are critical. The scope of this book is broad rather than deep with the intention of providing helpful insight. Much can be understood in a more qualitative way and that is the approach taken here. For those few areas where a quantitative approach is needed, simple mathematics will usually suffice.

Pulse and Fourier Transform NMR by Thomas C. Farrar,Edwin D. Becker Pdf

Pulse and Fourier Transform NMR: Introduction to Theory and Methods presents the different types of pulse experiments that are commonly used and provides the theoretical background necessary for understanding these techniques. This book evaluates the practical application of pulse methods and the necessary instrumentation. Organized into seven chapters, this book begins with an overview of the NMR fundamentals and the basic pulse methods. This text then summarizes the important features of pulse spectrometers. Other chapters consider the rationale, the advantages, and the limitations of Fourier transform NMR methods. This book discusses as well how the idea of the rotating frame can be utilized to understand certain experiments that extend the range of application of pulse methods. The final chapter deals with a few significant special uses of pulse techniques. This book is a valuable resource for chemists and readers who are familiar with high resolution NMR but with no background in pulse methods.

Modern Techniques in High-Resolution FT-NMR by Narayanan Chandrakumar,Sankaran Subramanian Pdf

The magnetism of nuclear spin systems has proved an amazingly fertile ground for the creativity of researchers. This happy circumstance results from the triple benediction that nature appears to have bestowed on nuclear spins: they are sporting spies-being infinitely manipulable (one is even tempted to say malleable), not unduly coy in revealing their secrets, and having a whole treasure house of secrets to reveal in the first place. researcher with Since spin dynamics are now orchestrated by the NMR ever more subtle scores, it is important to be able to tune into the pro ceedings with precision, if one is to make sense of it at all. Fortunately, it is not terribly difficult to do so, since in many ways spin dynamics are the theoretician's dream come true: they are often finite dimensional and quite tractable with basic quantum mechanics, frequently allowing near exact treatments and readily testable predictions. This book was conceived two years ago, with the objective of providing a simple, consistent introduction to the description of the spin dynamics that one encounters in modern NMR experiments. We believed it was a good time to attempt this, since it was possible by then to give sufficiently general descriptions of powelful classes of new NMR experiments. The choice of experiments we discuss in detail is necessarily subjective, al though we hope to have given a flavor of most of the important classes of pulse sequences, including some surface coil imaging applications.

Analysis of NMR Spectra by R. A. Hoffman,S. Forsen,B. Gestblom Pdf

Nuclear magnetic resonance spectroscopy, which has evolved only within the last 20 years, has become one of the very important tools in chemistry and physics. The literature on its theory and application has grown immensely and a comprehensive and adequate treatment of all branches by one author, or even by several, becomes increasingly difficult. This series is planned to present articles written by experts working in various fields of nuclear magnetic resonance spectroscopy, and will contain review articles as well as progress reports and original work. Its main aim, however, is to fill a gap, existing in literature, by publishing articles written by specialists, which take the reader from the introductory stage to the latest development in the field. The editors are grateful to the authors for the time and effort spent in writing the articles, and for their invaluable cooperation. The Editors Analysis of NMR Spectra A Guide for Chemists R. A.

NMR Spectroscopy in Organic Chemistry by B. I. Ionin Pdf

In recent years high-resolution nuclear magnetic resonance spec troscopy has found very wide application in organie chemistry in structural and physicochemical investigations and. also in the study of the characteristics of organic compounds which are re lated to the distribution of the electron cloud in the molecules. The vigorous development of this method, which may really be re garded as an independent branch of science, is the result of ex tensive progress in NMR technology, the refinement of its theory, and the accumulation of large amounts of experimental material, which has been correlated by empiricallaws and principles. The literature directly concerned with the NMR method and its applica tion has now grown to such an extent that a complete review of it is practically impossible. Therefore the authors have limited themselves to an examination of only the most important, funda mental, and general investigations. The book consists of six chapters. In the first chapter we have attempted to present the fundamentals of the NMR method in such a way that the reader with little knowledge of the subject will be able to use the method in practical work for investigating simple compounds and solving simple problems. The three subsequent chapters give a deeper analysis of the method, while the last two chapters and the appendix illustrate the various applications of NMR spectroscopy in organic chemistry.

Signal Treatment and Signal Analysis in NMR by D.N. Rutledge Pdf

Signal analysis and signal treatment are integral parts of all types of Nuclear Magnetic Resonance. In the last ten years, much has been achieved in the development of dimensional spectra. At the same time new NMR techniques such as NMR Imaging and multidimensional spectroscopy have appeared, requiring entirely new methods of signal analysis. Up until now, most NMR texts and reference books limited their presentation of signal processing to a short introduction to the principles of the Fourier Transform, signal convolution, apodisation and noise reduction. To understand the mathematics of the newer signal processing techniques, it was necessary to go back to the primary references in NMR, chemometrics and mathematics journals. The objective of this book is to fill this void by presenting, in a single volume, both the theory and applications of most of these new techniques to Time-Domain, Frequency-Domain and Space-Domain NMR signals. Details are provided on many of the algorithms used and a companion CD-ROM is also included which contains some of the computer programs, either as source code or in executable form. Although it is aimed primarily at NMR users in the medical, industrial and academic fields, it should also interest chemometricians and programmers working with other techniques.

NMR and Chemistry by J.W. Akitt,B. E. Mann Pdf

Keeping mathematics to a minimum, this book introduces nuclear properties, nuclear screening, chemical shift, spin-spin coupling, and relaxation. It is one of the few books that provides the student with the physical background to NMR spectroscopy from the point of view of the whole of the periodic table rather than concentrating on the narrow applications of 1H and 13C NMR spectroscopy. Aids to structure determination, such as decoupling, the nuclear Overhauser effect, INEPT, DEPT, and special editing, and two dimensional NMR spectroscopy are discussed in detail with examples, including the complete assignment of the 1H and 13C NMR spectra of D-amygdain. The authors examine the requirements of a modern spectrometer and the effects of pulses and discuss the effects of dynamic processes as a function of temperature or pressure on NMR spectra. The book concludes with chapters on some of the applications of NMR spectroscopy to medical and non-medical imaging techniques and solid state chemistry of both I = F1/2 and I > F1/2 nuclei. Examples and problems, mainly from the recent inorganic/organometallic chemistry literature support the text throughout. Brief answers to all the problems are provided in the text with full answers at the end of the book.
