FINE SHIMMING

Parameters:

probe = Z116098_0562
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.
Iteration  1: LSQ Before= 1.358 Hz, Target= 0.389 Hz, After= 0.445 Hz
Iteration  2: LSQ Before= 0.445 Hz, Target= 0.315 Hz, After= 0.535 Hz
Iteration  3: LSQ Before= 0.535 Hz, Target= 0.521 Hz, After= 0.599 Hz
Iteration  4: LSQ Before= 0.599 Hz, Target= 0.359 Hz, After= 0.492 Hz
Iteration  5: LSQ Before= 0.492 Hz, Target= 0.413 Hz, After= 0.588 Hz
Iteration  6: LSQ Before= 0.588 Hz, Target= 0.404 Hz, After= 0.460 Hz
Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, spinning) =  0.445 Hz (FWHM = 0.38 Hz)
