[Question from NMRWiki Q&A forum] 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...

NMR relaxation methods probe biomolecular motions over a wide range of timescales. In particular, the rotating frame spin-lock R1? and Carr-Purcell-Meiboom-Gill (CPMG) R2 experiments are commonly used to characterize ?sec-msec dynamics, which...

PhD in Soft Matter and RheoNMR
PhD in Soft Matter and RheoNMR
We seek applications from national and international students who have graduated in physics or chemistry, preferably with a background in NMR.The research will be in the field of soft matter (complex fluids investigated by means of Rheo-NMR under high shear rates, application of multidimensional NMR methods) with the focus on spatio-temporal fluctuations in banded-flow, wall slip effects and start up flow of micellar, polymeric and colloidal particles based on fast 3D NMR velocimetry. The research to be undertaken concerns addressing fundamental questions...
