WebProton nuclear magnetic resonance (proton NMR, hydrogen-1 NMR, or 1 H NMR) is the application of nuclear magnetic resonance in NMR spectroscopy with respect to hydrogen … WebA nucleus of an odd atomic/mass number has a nuclear spin that can be observed by the NMR spectrometer. A proton is the simplest nucleus with an odd atomic number of 1, implying it has a spin. We can visualize a spinning proton as a rotating sphere of positive charge. This movement of charge generates a magnetic field, called the magnetic ...
