FINE SHIMMING

Parameters:

probe = Z108618_0305
solvent = CDCl3
shim nucleus = 2H
nucleus optimised for = 1H
o1p (from lock) = 7.24 ppm

Results:


1D Shimming:
Low S/N encountered. The acquisition parameters will be changed to improve this issue.
echo time must be reduced
Iteration  1: FWHM Before= 0.5 Hz, Target= 0.6 Hz, After= 0.6 Hz
Iteration  2: FWHM Before= 0.6 Hz, Target= 0.4 Hz, After= 0.3 Hz
Iteration  3: FWHM Before= 0.3 Hz, Target= 0.2 Hz, After= 0.6 Hz
Iteration  4: FWHM Before= 0.6 Hz, Target= 0.2 Hz, After= 0.8 Hz
Iteration  5: FWHM Before= 0.8 Hz, Target= 0.3 Hz, After= 0.4 Hz
Iteration  6: FWHM Before= 0.4 Hz, Target= 0.6 Hz, After= 0.5 Hz
Iteration  7: FWHM Before= 0.5 Hz, Target= 0.2 Hz, After= 0.4 Hz
Diverging behaviour detected. Shimming was aborted.
Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, spinning) = 0.876
