FINE SHIMMING

Parameters:

probe = Z159656_0020
solvent = CDCl3
shim nucleus = 2H
nucleus optimised for = 1H
o1p (from lock) = 7.24 ppm

Results:


1D Shimming:
Iteration 1: FWHM Before= 0.3 Hz, Target= 0.3 Hz, After= 0.3 Hz
Iteration 2: FWHM Before= 0.3 Hz, Target= 0.4 Hz, After= 0.6 Hz
Iteration 3: FWHM Before= 0.6 Hz, Target= 0.3 Hz, After= 3.3 Hz
Iteration 4: FWHM Before= 3.3 Hz, Target= 0.3 Hz, After= 4.5 Hz
Iteration 5: FWHM Before= 4.5 Hz, Target= 0.3 Hz, After= 3.2 Hz
Iteration 6: FWHM Before= 3.2 Hz, Target= 0.3 Hz, After= 0.4 Hz
Iteration 7: FWHM Before= 0.4 Hz, Target= 0.2 Hz, After= 1.7 Hz
Iteration 8: FWHM Before= 1.7 Hz, Target= 0.3 Hz, After= 1.9 Hz
Unusually slow convergence detected. Shimming was aborted.
Using the best result as the final shim state.

Lineshape quality factor (1D shimming, non-spinning) = 0.57
