PC71d: 1D double quantum excitation POST_C7 pulse program for TopSpin2.1
PC71d: 1D double quantum excitation POST_C7 pulse program for TopSpin2.1
Since non-phase cycling is applied to the PC7 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 PC7 reconversion pulse for filtering DQ coherences.
