[Question from NMRWiki Q&A forum] Problem with the gradient shimming
Problem with the gradient shimming
Dear Friends,
I've recently encountered a problem with gradient shimming that has never happened to me before. I can't clearly determine what caused it but it certainly didn't involve anybody manipulating with the probe. Here's the symptom: when running the gmapz experiment, the Z-profiles (before and after gradient) look like this:

As you can see the second profile (after the gradient) is distorted at the left edge (more or less severely, depending on a sample - here it's just a tiny "step")....

shimming
Hello
Dose any one can estimate how are the results of shimming depend on the spectral character of the shim standard ? (for any NMR system)
For example using single peak vs 2 peak material such as water or xylene
Thanks
