Sample: ASTM Solvent: C6D6 Spectrometer: AVANCE 500 Probehead: Inverse Broadband with z-Gradients Experiment: High-power Decoupler 1H pulse calibration Pulse program: decp90 ( Pulse Diagram) Experiment Time: 10 minutes Details: AVANCE Tutorial

This pulse calibration is performed using the paropt AU program. pl2 is set to -3dB and p3 is varied from 0 to 15 microseconds using a 1 microsecond step. With p3=0, we observe an antiphase triplet, with the two outer lines in phase and the center line in opposite phase. P3 is increased until this triplet becomes nul (in our case , 6 microseconds). An analog procedure is followed for the Low-power ¹H Decoupler Pulse Calibration (for CPD)
