Applications of Nuclear Magnetic Resonance Spectroscopy in Organic Chemistry, Second Edition focuses on the applications of nuclear magnetic resonance spectroscopy to problems in organic chemistry and the theories involved in this kind of spectroscopy. The book first discusses the theory of nuclear magnetic resonance, including dynamic and magnetic properties of atomic nuclei, nuclear resonance, and relaxation process. The manuscript also examines the experimental method. Topics include experimental factors that influence resolution and the shapes of absorption lines; measurement of line positions and identification of the chemical shift; and measurement of intensities. The text reviews the theories of chemical effects in nuclear magnetic resonance spectroscopy and spin-spin multiplicity and the theory and applications of multiple irradiation. The book also tackles the theory of chemical shift, including the classification of shielding effects, local diamagnetic proton shielding, solvent effects, and contact shifts. The publication is a dependable source of data for readers interested in the applications of nuclear magnetic resonance spectroscopy.

Applications of NMR Spectroscopy is a book series devoted to publishing the latest advances in the applications of nuclear magnetic resonance (NMR) spectroscopy in various fields of organic chemistry, biochemistry, health and agriculture. The sixth volume of the series features reviews focusing on NMR spectroscopic techniques for studying tautomerism, applications in medical diagnosis, in food chemistry and identifying secondary metabolites.

An Introduction to Spectroscopic Methods for the Identification of Organic Compounds, Volume 1: Nuclear Magnetic Resonance and Infrared Spectroscopy discusses how spectral data can be translated into the structural formula of organic compounds and provides reference data and revised correlation tables for the initiated. The text describes high resolution nuclear magnetic resonance spectroscopy; the applications of nuclear magnetic resonance spectroscopy in organic chemistry; and correlation tables for nuclear magnetic resonance spectra. Nuclear magnetic resonance spectroscopy seminar problems and answers; the theoretical basis of infrared spectroscopy; and the applications of infrared spectroscopy to organic chemistry are also encompassed. The book further tackles infrared spectroscopic problems and answers, as well as correlation tables for infrared spectra.

This book demonstrates the usefulness of NMR spectroscopy for a wide variety of applications in environmental science and technology. It contains a wealth of information relating to instrumentation, sample preparation, and data interpretation. The book is divided into three sections discussing contaminant interaction, solution and condensed-phase characterization, and nutrients and natural organic matter characterization. In addition to these in-depth chapters, an introductory overview provides the basic principles of solution and solid-state NMR spectroscopy. Each section also contains a discussion of advances in each area directly attributable to NMR spectroscopy. A final chapter suggests future directions for the deployment of this powerful technology in environmental science.
