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= 7.8 Hz, Target= 0.3 Hz, After= 3.1 Hz
Iteration  2: FWHM Before= 3.1 Hz, Target= 0.4 Hz, After= 4.2 Hz
Iteration  3: FWHM Before= 4.2 Hz, Target= 0.8 Hz, After= 2.1 Hz
Iteration  4: FWHM Before= 2.1 Hz, Target= 0.4 Hz, After= 3.9 Hz
Iteration  5: FWHM Before= 3.9 Hz, Target= 0.4 Hz, After= 3.7 Hz
Iteration  6: FWHM Before= 3.7 Hz, Target= 2.0 Hz, After= 2.2 Hz
Iteration  7: FWHM Before= 2.2 Hz, Target= 1.3 Hz, After= 1.3 Hz
Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, spinning) = 2.81
