Application of nuclear magnetic resonance spectroscopy to solids.
Note: SSNMR is characterized by the presence of anisotropic (directionally dependent) interactions. Chemical shift anisotropy (CSA) and internuclear dipolar coupling result in severe line-broadening of the corresponding NMR signals and specific hardware and methods are required to perform SSNMR to mitigate some of these issues including magic angle spinning (MAS).
