FINE SHIMMING

Parameters:

probe = Z168793_0014
solvent = D2O
shim nucleus = 2H
nucleus optimised for = 1H
o1p (from lock) = 4.70 ppm

Results:


1D Shimming:
Iteration  1: FWHM Before=140.2 Hz, Target= 0.3 Hz, After=97.7 Hz
echo time must be reduced
Iteration  2: FWHM Before=97.7 Hz, Target= 0.6 Hz, After= 0.3 Hz
Iteration  3: FWHM Before= 0.3 Hz, Target= 1.2 Hz, After= 0.2 Hz
Iteration  4: FWHM Before= 0.2 Hz, Target= 1.5 Hz, After=18.0 Hz
Iteration  5: FWHM Before=18.0 Hz, Target= 0.9 Hz, After= 6.6 Hz
Iteration  6: FWHM Before= 6.6 Hz, Target= 0.8 Hz, After= 0.7 Hz
Iteration  7: FWHM Before= 0.7 Hz, Target= 0.5 Hz, After=23.7 Hz
Iteration  8: FWHM Before=23.7 Hz, Target= 0.9 Hz, After= 0.1 Hz
Unusually slow convergence detected. Shimming was aborted.
Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, spinning) = 0.759
