The field of nuclear magnetic resonance spectroscopy has undergone explosive development during the last decade with the advent of new one- and two-dimensional techniques. The author has had extensive experience in the use of these techniques for the structure elucidation of complex natural products, and in this book he gives a comprehensive, up-to-date and very readable account of these developments. The book's scope is very wide. It starts from fundamental principles of modern NMR spectroscopy, describing the instrumentation and its optimum use, and extends to the latest developments such as inverse measurements. Emphasis is on problem-solving so as to be useful to a large number of organic chemists, biochemists and medicinal chemists. The problems and worked solutions at the end of the chapters will help students to gain proficiency in the application of these new techniques. Those who are learning how to operate modern NMR spectrometers will find particularly useful the description of such basic aspects as shimming, probe tuning, and methods for improvement of resolution and sensitivity.

The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. Over recent years, a number of powerful two–dimensional NMR techniques (e.g. HSQC, HMBC, TOCSY, COSY and NOESY) have been developed and these have vastly expanded the amount of structural information that can be obtained by NMR spectroscopy. Improvements in NMR instrumentation now mean that 2D NMR spectra are routinely (and sometimes automatically) acquired during the identification and characterisation of organic compounds. Organic Structures from 2D NMR Spectra is a carefully chosen set of more than 60 structural problems employing 2D–NMR spectroscopy. The problems are graded to develop and consolidate a student s understanding of 2D NMR spectroscopy. There are many easy problems at the beginning of the collection, to build confidence and demonstrate the basic principles from which structural information can be extracted using 2D NMR. The accompanying text is very descriptive and focussed on explaining the underlying theory at the most appropriate level to sufficiently tackle the problems. Organic Structures from 2D NMR Spectra Is a graded series of about 60 problems in 2D NMR spectroscopy that assumes a basic knowledge of organic chemistry and a basic knowledge of one–dimensional NMR spectroscopy Incorporates the basic theory behind 2D NMR and those common 2D NMR experiments that have proved most useful in solving structural problems in organic chemistry Focuses on the most common 2D NMR techniques including COSY, NOESY, HMBC, TOCSY, CH–Correlation and multiplicity–edited C–H Correlation. Incorporates several examples containing the heteronuclei 31P, 15N and 19F Organic Structures from 2D NMR Spectra is a logical follow–on from the highly successful Organic Structures from Spectra which is now in its fifth edition. The book will be invaluable for students of Chemistry, Pharmacy, Biochemistry and those taking courses in Organic Chemistry.

Organic Structures from 2D NMR Spectra is complimented by the Instructors Guide and Solutions Manual to Organic Structures from 2D NMR Spectra which is a set of step–by–step worked solutions to every problem in the book. While it is absolutely clear that there are many ways to get to the correct solution of any of the problems, the instructors guide contains at least one complete pathway to every one of the questions. In addition, the instructors guide carefully rationalises every peak in every spectrum in relation to the correct structure. The Instructors Guide and Solutions Manual to Organic Structures from 2D NMR Spectra: – Is a complete set of worked solutions to the problems contained in Organic Structures from 2D NMR Spectra. – Provides a step–by–step description of the process to derive structures from spectra as well as annotated 2D spectra indicating the origin of every cross peak. – Highlights common artefacts and re–enforces the important characteristics of the most common techniques 2D NMR techniques including COSY, NOESY, HMBC, TOCSY, CH–Correlation and multiplicity–edited C–H Correlation.

This volume covers the new methodological advances in NMR spectroscopy that have been developed since the publication of the first edition. These include: 'indirect detection' methods, particularly proton-detected carbon-13 spectra, which have profoundly increased NMR sensitivities; 3- and even higher- dimensional NMR methods which have further increased spectral resolving and correlating power; powerful new computer programs which assist in all phases of data analysis and ultimately make possible rigorous interpretations of complex 2D and higher- dimensional NMR spectra using molecular mechanics and dynamics calculations; and field gradient technology which makes it possible to acquire 2D and higher-dimensional spectra of concentrated samples very rapidly, greatly reducing experiment times. This new edition retains the original format of the first edition with introductory chapters covering descriptions, basic theoretical treatments and experimental aspects of the methods. These are followed by applications chapters representing a broad sampling of important research areas and compound classes

This second, thoroughly revised, updated and enlarged edition provides a straightforward introduction to spectroscopy, showing what it can do and how it does it, together with a clear, integrated and objective account of the wealth of information that may be derived from spectra. It also features new chapters on spectroscopy in nano-dimensions, nano-optics, and polymer analysis. Clearly structured into sixteen sections, it covers everything from spectroscopy in nanodimensions to medicinal applications, spanning a wide range of the electromagnetic spectrum and the physical processes involved, from nuclear phenomena to molecular rotation processes. In addition, data tables provide a comparison of different methods in a standardized form, allowing readers to save valuable time in the decision process by avoiding wrong turns, and also help in selecting the instrumentation and performing the experiments. These four volumes are a must-have companion for daily use in every lab.

An integrated chemical and microbial approach was used to study the effects of chemical structure on rates and patterns of carbohydrate degradation by anaerobic marine bacteria. Nuclear magnetic resonance spectroscopy (NMR) was used to characterize plankton carbohydrates, and to follow the bacterial hydrolysis of polysaccharides. A carbohydrate produced by Synechococcus WH7335 was identified as a teichoic acid-like polysaccharide, similar in structure to teichoic acids found in cell walls of gram-positive bacteria. This is the first report of teichoic acids in cyanobacteria. Enrichment experiments with bacteria from anoxic marine sediments showed that mixed cultures of marine bacteria distinguish even between small, very closely-related substrates which do not require extracellular hydrolysis prior to uptake. A series of experiments showed that polysaccharides are degraded by bacteria at virtually the same rate as structurally related substrates in the molecular weight range of 300-600 daltons. The time-course of pullulan degradation was examined with gel permeation chromatography and NMR to provide the first molecular-level evidence in marine systems of the bacterial extracellular hydrolysis of high molecular weight organic matter to lower molecular weight organic matter. The experiments demonstrate that enzymatic hydrolysis of macromolecules is not always the slow step in bacterial degradation of organic matter. Carbohydrate, Bacteria, NMR.
