A new three-pulse sequence was designed to choose signals from intermolecular ZQCs and avoid contamination from other coherences, using intermolecular double-quantum filtering. Efficient phase-cycling and fast spin echo acquisition with optimal flip angles were proposed to obtain pure iZQC images quickly, to overcome the imperfect RF pulses, and to reduce the effect of the longitudinal magnetization during the evolution period. The method may provide an attractive alternative for iZQC with the CRAZED sequence.
