NMR Experiments for half-integer quadrupolar nuclei

MAS

Double Rotation (DOR) achives high-resolution spectra of the central transitions by spinning the sample simultaneously at two angles

Dynamic-angle spinning (DAS): 2D experiment which achieves isotropic signals in one dimension and quadrupolar-broadened anisotropic powder patterns in the other.

MQMAS correlates a multiple-quantum transition with the central transition

Satellite transition magic-angle spinning (STMAS) correlates a satellite transition with the central transition
