200 And More Nmr Experiments

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

This book is the perfect link for learning how to perform the experiments after only having studied theory. In eight chapters more than 50 essential NMR experiments are described in detail. Special focus is put on the organic set of NMR spectra (1H, 13C-APT, COSY, NOESY, HSQC and HMBC). Different chapters deal with advanced organic NMR, selective methods, heteronuclear NMR, relaxation and diffusion measurements, organic applications and maintenance. Every experiment has a section providing the reader with the purpose and scope of the specific experiment. Every experiment is concluded with the spectrum as it is obtained under the conditions described. Questions and comments enable the reader to check their understanding. The authors are very experienced and the whole book is in full color, which enhances the reading experience and makes the spectra and other figures easier to understand. This book is strongly recommended for all students and researchers who are involved in the structural elucidation of chemical compounds both in practical education and in pursuing research, in particular if they handle an NMR spectrometer.

NMR is one of the most widely used analytical techniques in chemistry. This book gives a problem-oriented introduction to modern applications in a "how-to" format.

Nuclear Magnetic Resonance (NMR) spectroscopy, a physical phenomenon based upon the magnetic properties of certain atomic nuclei, has found a wide range of applications in life sciences over recent decades. This up-to-date volume covers NMR techniques and their application to proteins, with a focus on practical details. Providing newcomers to NMR with practical guidance to carry out successful experiments with proteins and analyze the resulting spectra, those familiar with the chemical applications of NMR will also find it useful in understanding the special requirements of protein NMR.

The key to correct structure analysis. This volume of the successful "Spectroscopic Techniques" series familiarizes newcomers with the basic data acquisition procedures, modular pulse sequence units and complete sequences in NMR spectroscopy. It applies the numerous possibilities of Bruker's simulation program NMR-SIM to provide a guided introduction to the world of pulse sequences. The effectiveness of particular NMR experiments is demonstrated by the section "Check Its" and that of data processing by the accompanying CD-ROM with the Bruker processing software 1D and 2D WIN-NMR. This interactive approach to simulate spectra based on a reduced spin system and the processing of the accomplished NMR raw data is closely related to everyday work at the spectrometer. In this way, the author encourages beginners to use high resolution NMR, and also experts on NMR spectroscopy to evaluate new experiments using the easy-manageable simulation program.

This text is aimed at people who have some familiarity with high-resolution NMR and who wish to deepen their understanding of how NMR experiments actually ‘work’. This revised and updated edition takes the same approach as the highly-acclaimed first edition. The text concentrates on the description of commonly-used experiments and explains in detail the theory behind how such experiments work. The quantum mechanical tools needed to analyse pulse sequences are introduced set by step, but the approach is relatively informal with the emphasis on obtaining a good understanding of how the experiments actually work. The use of two-colour printing and a new larger format improves the readability of the text. In addition, a number of new topics have been introduced: How product operators can be extended to describe experiments in AX2 and AX3 spin systems, thus making it possible to discuss the important APT, INEPT and DEPT experiments often used in carbon-13 NMR. Spin system analysis i.e. how shifts and couplings can be extracted from strongly-coupled (second-order) spectra. How the presence of chemically equivalent spins leads to spectral features which are somewhat unusual and possibly misleading, even at high magnetic fields. A discussion of chemical exchange effects has been introduced in order to help with the explanation of transverse relaxation. The double-quantum spectroscopy of a three-spin system is now considered in more detail.
