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= 0.8 Hz, Target= 0.4 Hz, After= 1.5 Hz
Iteration  2: FWHM Before= 1.5 Hz, Target= 0.4 Hz, After= 0.3 Hz
Iteration  3: FWHM Before= 0.3 Hz, Target= 0.2 Hz, After= 2.0 Hz
Iteration  4: FWHM Before= 2.0 Hz, Target= 0.9 Hz, After= 1.0 Hz
Iteration  5: FWHM Before= 1.0 Hz, Target= 0.6 Hz, After= 1.1 Hz
Iteration  6: FWHM Before= 1.1 Hz, Target= 0.9 Hz, After= 1.2 Hz
Using the best result as the final shim state.
