Basic One And Two Dimensional Nmr Spectroscopy

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.

This is the fifth edition of the highly successful, classic textbook for bachelor and master courses, with over 20 % new material and the contents completely revised and updated. Using a minimum of mathematics, it explains the underlying theory of this most important spectroscopic technique in a thorough, yet readily understandable way, covering instrumentation and interpretation of the spectra. It presents all students need to know about 1D, 2D-NMR, solid state and dynamic NMR spectroscopy, as well as NMR imaging, all illustrated by examples for maximum clarity. All the sections include sub-chapters that focus on applications taken from organic, macromolecular, polymer and biochemistry. A must for students and lecturers in chemistry, biochemistry, pharmacy, and life sciences, as well as for spectroscopists.

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.

Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful and widely used techniques in chemical research for investigating structures and dynamics of molecules. Advanced methods can even be utilized for structure determinations of biopolymers, for example proteins or nucleic acids. NMR is also used in medicine for magnetic resonance imaging (MRI). The method is based on spectral lines of different atomic nuclei that are excited when a strong magnetic field and a radiofrequency transmitter are applied. The method is very sensitive to the features of molecular structure because also the neighboring atoms influence the signals from individual nuclei and this is important for determining the 3D-structure of molecules. This new edition of the popular classic has a clear style and a highly practical, mostly non-mathematical approach. Many examples are taken from organic and organometallic chemistry, making this book an invaluable guide to undergraduate and graduate students of organic chemistry, biochemistry, spectroscopy or physical chemistry, and to researchers using this well-established and extremely important technique. Problems and solutions are included.

Diese Neuauflage behandelt auch die methodischen Fortschritte in der NMR-Spektroskopie, die seit der ersten Auflage gemacht wurden. Dazu gehören die indirekten Nachweismethoden, die die Empfindlichkeit wesentlich gesteigert haben; die drei- und mehrdimensionale NMR mit ihrer erhöhten spektralen Auflösung und Korrelationsvermögen; neue Programme, die die Molekularmechanik und dynamische Rechnungen ausnutzen und mit denen man komplexe zwei- und mehrdimensionale NMR- Spektren genau auswerten kann; und das Gradientenverfahren, das die Untersuchungszeit wesentlich verkürzt. Die Neuauflage behält den bewährten Aufbau der ersten Ausgabe bei: Einführende Kapitel mit Beschreibungen, den Grundlagen der Theorie und den experimentellen Aspekten stehen Anwendungskapiteln voran, die die Breite der Forschungsgebiete und Verbindungsklassen illustrieren. Aus Besprechungen der ersten Auflage: ... mit seinem einzigartigen Inhalt und praktischen Wert wird es seinen Platz auf den Bücherbrettern der meisten NMR-Laboratorien finden.
