Can the spinning and non-spinning shims on the line shape sample over a time
can show what is happening?

Ken - a friendly reminder that if you are indeed battling a temperature gradient,
topshim now gives us the "tcorr" option to apply a correction. We use tcorr routinely
here for aqueous samples on a TCI Prodigy.

Even if your version of topshim does not allow "tcorr" yet, you could achieve the
same effect via a simple AU program as part of your shimming routine in iconnmr
for aqueous solvents.

Good Luck!
Mike
