SPC5CP2d: 2D double quantum excitation phase-inversion supercycled POST-C5 CP pulse program for TopSpin2.1
SPC5CP2d: 2D double quantum excitation phase-inversion supercycled POST-C5 CP pulse program for TopSpin2.1
Since non-phase cycling is applied to the SPC5 excitation pulse, four-phase cycling is applied to the detection pulse P1 for selecting the 0Q -> -1Q coherence order jump, and four-phase cycling is applied to the SPC5 reconversion pulse for filtering DQ coherences.
Avoid cross-polarization during SPC5 excitation and reconversion.
