For some reason the shape tool has some sort of glitch that I can't calculate a power level for a wurst 10 ms pulse 180 rotation for a a 522 max gamma ~ for over 3000 Hz, with an option "Analyze adiabatic shape". It insists it is not an adiabatic shape. So I tried opening the same file shape tool in XWIN-NMR shape tool and the same problem occured but this time it gave me the Hz covered in maximum gamma when I included the degrees of rotation as well as the time for the pulse. it covers a 3ppm bandwidth etc. I think I've done this many years ago but can't find my notes on it. Is there a way to calculate this? Thanks. R |

I've used edprosol to do this too; it seems to work ok with the standard adiabatic experiments eg hsqcetgpsisp2.3. For it to work your instrument will need to be cortabbed though I would say. (So the output in watts to the probe is linearised across the attenuation range) Duncan |

You can try to use edprosol to calculate the power level of the shaped pulse. I use this methodology because it is more quick to obtain the value than via stdisp. |
