Default Chemical shift evolution compensation for delays flanked by hard or soft pulses
Chemical shift evolution compensation for delays flanked by hard or soft pulses

Hello all,In a typical 2D experiment, the delay "d0" (t1 increment delay in Bruker) is compensated for the chemical shift evolution that would happen during the rf pulse (hard/soft) that are applied flanking (before and after) the "d0" delay.

I could also find similar such compensations for shaped pulses before a delay in the pulse programs. These compensation factors varies for different types of pulses, e.g. 2/pi for 90 hard pulse , 0.52 for pc490120. Can someone guide me how these compensation factors are calculated for hard as well as shaped pulses? Thanks!
