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= 1.3 Hz, Target= 0.5 Hz, After= 0.3 Hz
Iteration 2: FWHM Before= 0.3 Hz, Target= 0.9 Hz, After= 1.3 Hz
Iteration 3: FWHM Before= 1.3 Hz, Target= 0.4 Hz, After= 5.3 Hz
Iteration 4: FWHM Before= 5.3 Hz, Target= 0.2 Hz, After= 0.3 Hz
Iteration 5: FWHM Before= 0.3 Hz, Target= 0.3 Hz, After= 0.3 Hz
Iteration 6: FWHM Before= 0.3 Hz, Target= 0.2 Hz, After= 0.8 Hz
Iteration 7: FWHM Before= 0.8 Hz, Target= 0.3 Hz, After= 0.3 Hz
Iteration 8: FWHM Before= 0.3 Hz, Target= 0.2 Hz, After= 1.2 Hz
Unusually slow convergence detected. Shimming was aborted.
Using the best result as the final shim state.

Lineshape quality factor (1D shimming, non-spinning) = 0.577
