Reihe: Annual Reports on NMR Spectroscopy

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 gained such significance as NMR spectroscopy. It is used in all branches of science in which precise structural determination is required and in which the nature of interactions and reactions in solution is being studied. Annual Reports on NMR Spectroscopy has established itself as a premier means for the specialist and non-specialist alike to become familiar with new techniques and applications of NMR spectroscopy. - Provides updates on the latest developments in NMR spectroscopy - Includes comprehensive review articles - Highlights the increasing importance of NMR spectroscopy as a technique for structural determination
