title: Synchronized double rotation 2D NMR.
abstract: Analytical expressions for multi-quantum signal generation of quadrupole nuclei have been derived. Combined with numerical simulation of the double rotor motion, a strategy is suggested for partial sideband suppression in multi-quantum NMR spectra. Synchronization of multi-quantum excitation and selective flip pulses with outer rotor motion increase outer rotor speed effectively two times. This is also demonstrated experimentally by triple-single quantum correlation spectra of 23Na and 67Rb.
