NMR SPECTROSCOPY NMR stands for nuclear magnetic resonance. PMR or "HNMR stands for proton magnetic resonance, which is the type of magnetic resonance that will be specifically discussed. PMR is a spectroscopic technique that allows the detection of hydrogen atoms in molecules. Different kinds of hydrogens as well as the relative numbers of each kind of hydrogen can be detected. PMR is a powerful tool for determining the structures of organic molecules. Exercises These exercises are to be done in...
