Modulated-RF MQ-MAS references

Below are provided some NMR references about MQ-MAS with modulated RF pulse sequence applied to half-integer quadrupole spins. These references contain
(1) the pulse-sequence diagram,
(2) the coherence-transfer pathways,
(3) the phase-cycling,
(4) the receiver-phase relationship.
