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: FWHM Before= 0.4 Hz, Target= 0.5 Hz, After= 0.8 Hz
Iteration  2: FWHM Before= 0.8 Hz, Target= 0.6 Hz, After= 0.8 Hz
Iteration  3: FWHM Before= 0.8 Hz, Target= 0.6 Hz, After= 0.9 Hz
Iteration  4: FWHM Before= 0.9 Hz, Target= 0.7 Hz, After= 1.8 Hz
Iteration  5: FWHM Before= 1.8 Hz, Target= 1.3 Hz, After= 1.9 Hz
Iteration  6: FWHM Before= 1.9 Hz, Target= 1.6 Hz, After= 1.7 Hz
Iteration  7: FWHM Before= 1.7 Hz, Target= 0.7 Hz, After= 1.2 Hz
Using the best result as the final shim state.
