Residual chemical shift anisotropy

Residual chemical shift anisotropy

Residual chemical shift anisotropy (RCSA) is the difference between the chemical shift anisotropy (CSA) of aligned and non-aligned molecules. It is normally three orders of magnitide smaller than static CSA. RCSA is useful for structural determination and it is among the new developments in NMR spectroscopy.
