Intermolecular Double-quantum-filtered Zero-quantum Coherence in Liquid NMR
Zhu X, Chen Z, Cai S, Zhong J
A double-quantum filtered iZQC pulse sequence was proposed to detect iZQC signals from isolated spin-1/2 systems. Compared to the two-pulse CRAZED sequence for iZQC, the new sequence is insensitive to the imperfection of flip angles thus less susceptible to contaminations of other coherence orders. Experimental observations and computer simulations are in good agreement with the theoretical predictions.
