With the advent of Fourier transform spectrometers of great sensitivity, it has become practical to obtain carbon-13 nuclear magnetic resonance (C-13 NMR; l3C NMR; CMR) spectra routinely on organic molecules, and this technique has become one of the highest utility in determining structures of organic unknowns. When the usual spectrometric techniques proton magnetic resonance (H-I NMR; IH NMR; PMR), infrared (lR), mass (MS), and ultraviolet (UV)-do not readily reveal a compound's structure, a C-13 NMR spectrum will often provide sufficient additional information to yield it unequivocally. With this in mind, the present work was designed to give advanced undergraduates, graduate students, and practicing chemists a working knowledge of and facility with the use of this valuable technique. Some familiarity with other spectrometric techniques is assumed (recommended book: Silverstein, Bassler, and Morrill, Spectrometric Identification of Organic Compounds), but no prior knowledge of C-13 NMR -which is treated very lightly, if at all, in the widely used elementary organic texts-is necessary. A discussion of C-13 NMR spectroscopy is followed by 125 problems, each consisting of a molecular formula, two types of C-13 NMR spectra (partially and completely proton decoupled, with connecting lines to facilitate multiplicity assignments), an integrated H-I NMR spectrum, and the most important IR, UV, and MS data. These problems have been very carefully prepared, thoroughly tested by students at the University of Arizona, and we believe that very few errors remain.

The text Organic Structures from 2D NMR Spectra contains a graded set of structural problems employing 2D-NMR spectroscopy. The Instructors Guide and Solutions Manual to Organic Structures from 2D NMR Spectra is a set of step-by-step worked solutions to every problem in Organic Structures from 2D NMR Spectra. 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 guide is an essential aid to those teachers, lecturers and instructors who use Organic Structures from 2D NMR as a text to teach students of Chemistry, Pharmacy, Biochemistry and those taking courses in Organic Chemistry.

Organic Structures from Spectra, Fourth Edition consists of a carefully selected set of over 300 structural problems involving the use of all the major spectroscopic techniques. The problems are graded to develop and consolidate the student’s understanding of Organic Spectroscopy, with the accompanying text outlining the basic theoretical aspects of major spectroscopic techniques at a level sufficient to tackle the problems. Specific changes for the new edition will include A significantly expanded section on 2D NMR spectroscopy focusing on COSY, NOESY and CH-Correlation Incorporating new material into some tables to provide extra characteristic data for various classes of compounds Additional basic information on how to solve spectroscopic problems Providing new problems within the area of 10 2D NMR spectroscopy More problems at the ‘simpler’ end of the range As with previous editions, this book combines basic theory, practical advice and sensible approaches to solving spectra problems. It will therefore continue to prove invaluable to students studying organic spectroscopy across a range of disciplines.

The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. A critical part of any such course is a suitable set of problems to develop the students’ understanding of how organic structures are determined from spectra. The book builds on the very successful teaching philosophy of learning by hands-on problem solving; carefully graded examples build confidence and develop and consolidate a student’s understanding of organic spectroscopy. Organic Structures from Spectra, 6th Edition is a carefully chosen set of about 250 structural problems employing the major modern spectroscopic techniques, including Mass Spectrometry, 1D and 2D 13C and 1H NMR Spectroscopy and Infrared Spectroscopy. There are 25 problems specifically dealing with the interpretation of spin–spin coupling in proton NMR spectra and 10 problems based on the quantitative analysis of mixtures using proton and carbon NMR spectroscopy. The accompanying text is descriptive and only explains the underlying theory at a level that is sufficient to tackle the problems. The text includes condensed tables of characteristic spectral properties covering the frequently encountered functional groups. The examples themselves have been selected to include all important structural features and to emphasise connectivity arguments and stereochemistry. Many of the compounds were synthesised specifically for this book. In this collection, there are many additional easy problems designed to build confidence and to demonstrate basic principles. The Sixth Edition of this popular textbook: now incorporates many new problems using 2D NMR spectra (C–H Correlation spectroscopy, HMBC, COSY, NOESY and TOCSY); has been expanded and updated to reflect the new developments in NMR spectroscopy; has an additional 40 carefully selected basic problems; provides a set of problems dealing specifically with the quantitative analysis of mixtures using NMR spectroscopy; features proton NMR spectra obtained at 200, 400 and 600 MHz and 13C NMR spectra including routine 2D C–H correlation, HMBC spectra and DEPT spectra; contains a selection of problems in the style of the experimental section of a research paper; includes examples of fully worked solutions in the appendix; has a complete set of solutions available to instructors and teachers from the authors. Organic Structures from Spectra, Sixth Edition will prove invaluable for students of Chemistry, Pharmacy and Biochemistry taking a first course in Organic Chemistry.
