New TopShim run:

version = topshim 2.4.0
date = 2026-09-28
time = 16:51:16.393
command = topshim  convcomp ordmax=4

FINE SHIMMING

Parameters:

probe = Z104275_0310
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.
echo time must be reduced
echo time must be reduced

NOTE: very poor map quality encountered despite the CONVCOMP option being used.

Required SINO has not been achieved!
Please increase DURMAX if a better map quality is needed.
