Nuclear magnetic resonance (NMR) is an analytical tool used by chemists and physicists to study the structure and dynamics of molecules. In recent years, no other technique has grown to such importance as NMR spectroscopy. It is used in all branches of science where precise structural determination is required and where the nature of interactions and reactions in solution is being studied.

Annual Reports on NMR has established itself as a premier means for the specialist and nonspecialist alike to become familiar with new techniques and applications of NMR spectroscopy....

Though many separation processes are available for use in todays analytical laboratory, chromatographic methods are the most widely used. The applications of chromatography have grown explosively in the last four decades, owing to the development of new techniques and to the expanding need of scientists for better methods of separating complex mixtures. With its comprehensive, unified approach, this book will greatly assist the novice in need of a reference to chromatographic techniques, as well as the specialist suddenly faced with the need to switch from one technique to another.

This text was developed from a course for physical chemistry and chemical physics students using cross-polarization (CP) magic angle spinning (MAS) NMR in their laboratory assignments. The book provides students with the details of the CP/MAS experiment as it is used to obtain rare-spin, high-resolution NMR spectra. The design of the CP/MAS experiments and the interpretation of spectra and relaxation measurements require an understanding of the interplay of several fundamental physical interactions not normally encountered in solution NMR. The student can observe the way interacting spin...

Chemical data analysis, with aspects of metrology in chemistry and chemometrics, is an evolving discipline where new and better ways of doing things are constantly being developed.

This book describes the main methods of one- and two-dimensional high-resolution nuclear magnetic resonance spectroscopy in liquids within the quantum-mechanical formalism of the density matrix. In view of the increasing importance of NMR in chemistry and biochemistry, the work is particularly addressed to those scientists who do not have a working knowledge of quantum calculations. This knowledge is provided in the first part of the book through a description of quantum mechanics as applied to spin systems. This section is self-contained and limited to essentials. A final chapter is devoted...

Nuclear magnetic resonance techniques have advanced dramatically in recent years, and are now more powerful and more versatile than ever before. In order to exploit these techniques efficiently, chemists must have both an understanding of the techniques' theoretical bases and the ability to interpret the spectra accurately. This workbook presents worked examples and set problems that cover one- and two-dimensional NMR techniques as applied to organic and inorganic systems. Most of the problems are genuine research examples, and this second edition contains numerous new problems derived from...

Matrix isolation is a technique for trapping reactive species at very low temperatures and studying them spectroscopically. This unique introduction to the subject offers detailed practical advice on how to carry out matrix-isolation experiments.

The intrinsic or natural fluorescence of proteins is perhaps the most complex area of biochemical fluorescence. Fortunately the fluorescent amino acids, phenylalanine, tyrosine and tryptophan are relatively rare in proteins. Tr- tophan is the dominant intrinsic fluorophore and is present at about one mole % in protein. As a result most proteins contain several tryptophan residues and even more tyrosine residues. The emission of each residue is affected by several excited state processes including spectral relaxation, proton loss for tyrosine, rotational motions and the presence of nearby...
