References for two-pulse MQ-MAS nutation NMR

The multi-quantum magic angle spinning (MQMAS) experiment on half-integer quadrupole spins was introduced by L. Frydman and co-workers. In the basic two-pulse sequence, it is an echo experiment involving transitions between non-consecutive energy levels during the excitation of the spin system by the first pulse.

References containing data and graphs that can be simulated with the MQ-MAS applets, in order to determine the quadrupole coupling from a featureless NMR lineshape, are provided:
