Learn about the physical phenomenon of NMR, which occurs when nuclei in a magnetic field respond to a weak oscillating field. Find out how NMR is used in spectroscopy, imaging, and condensed matter physics.
Theory The chemical theory that underlies NMR spectroscopy depends on the intrinsic spin of the nucleus involved, described by the quantum number S. Nuclei with a non-zero spin are always associated with a non-zero magnetic moment, as described by Equation 4.7.1 4.7.1, where μ is the magnetic moment, S S is the spin, and γ is always non-zero. It is this magnetic moment that allows for NMR to ...
