Advances in Magnetic Resonance

Advances in Magnetic Resonance: The Waugh Symposium, Volume 13 is a collection of manuscripts presented at the 1989 conference on "High Resolution NMR in Solids at Massachusetts Institute of Technology. This conference recognizes the accomplishments of John S. Waugh and his colleagues in the entire field of high resolution nuclear magnetic resonance (NMR) in solids.
Organized into 11 chapters, this book first discusses the principles, limitations, and applications of single crystal, deuterium, proton, and rotational-echo double resonance NMR techniques. It then deals with other NMR methods, such as two-dimensional, electrophoretic, and site-selective excitation NMR, with particular emphasis on their theoretical background and application in solid systems. Other chapters describe several hybrid two-dimensional experiments leading to a significant increase in spectral quality. Discussions on the advantages of utilizing two-dimensional solid-state NMR in studying the complex and highly orientable biological samples such as DNA are provided in the concluding chapters of the book. This volume also provides the 113Cd NMR results in the prediction of the 113Cd shielding tensor orientation in the real ligand geometry at a metal site.
Analytical and quantum chemists, physicists, biochemists, and materials science researchers will find this book invaluable.
