  • From "Experimental Pulse NMR - A Nuts and Bolts Approach" by Fukushima, P.11, he says " an appropriate combination of intensity and duration of the rotating field can rotate the magnetization by any desired amount...the rotating field H1 required to turn a proton magnetization by 90 deg. usually lasts between 1 and 50 microseconds in a modern pulse NMR experiment." With my RF power and coil I found empirically that 20-25us leads to the greatest intensity of the FID.

  • How did you arrive at the pulse duration of 20 seconds for the 90 degree pulse? Is it based on the frequency?
