Nuclear Magnetic Resonance (NMR) is a powerful relatively non-selective analytical tool, which enables you to ascertain molecular structure including relative configuration, relative and . The nuclear magnetic resonance (NMR) spectroscopy is of three types: Proton nuclear magnetic resonance (1HNMR) spectroscopy, carbon nuclear magnetic resonance (13CNMR) . nuclear magnetic resonance spectroscopy for determining the three-dimensional structure of biological macromolecules in solution • Paul C.
