Abstract
Here, we present a modified CPMG-HSQMBC experiment which is capable to reduce the detrimental phase twists in the “long-range” connectivity multiplets caused by proton-proton couplings. We demonstrate that concerted CPMG pulse trains applied on both nuclei in the starting CPMG-INEPT transfer step can considerably be improved by composite Ï pulses that compensate for pulse imperfections and off-resonance effects. Experimental optimization of the interpulse delay within the CPMG cycle was found to be crucial in order to achieve the best possible “decoupling” of homonuclear coupling modulation.
