Nuclear Magnetic Resonance 2

 NMR in solids, like solution-state, relies on the behavior of nuclear spin energy levels in a magnetic field. However, the interactions that affect NMR spectra act differently.  In liquids, molecules reorient and diffuse quickly, leading to narrow isotropic resonances.  In solids, the fixed orientation of individual crystallites leads to a range of resonance frequencies for anisotropic interactions.
