Does phase cycling work for nuclei experiencing strong quadrupolar couplings?

The question of whether the phase cycling can still be used to select coherence transfer pathways in spin systems experiencing a tilting of its eigenstates away from the Zeeman eigenstates due to strong couplings was investigated theoretically. Based on the analysis presented it is concluded that conventional phase cycling is still a valid approach for selecting a coherence transfer pathway signal, although changes in pathway efficiencies can occur as the mechanisms for excitation and detection of coherences are affected by the tilting of the eigenstates.
