Bad shimming for standard proton expt in CDCl3. Top trace is spectrum when shimming is working, bottom is current spectrum where shimming seems to not be working well
I got bad shimming leading to bad NMR signals.

sample loading error.
Automation has been stopped on the neo500 cannot run anything since last user submitted experiments: tonyvm’s run is not running. Remarks: automation stopped by user.
Sample Loading error. The light is red and no sample can be loaded.
Day/night queue error — running very long experiments during the day time.
Samples added to queue not running. Sample changer issue? Remarks column says “Webservice error: 1000 stop_changer”.
Won’t shim on d6-acetone, get error: Shim program failed: convcomp, error: invalid command name \ “convcomp\” , Shim failed. Spectra has no resolution, can’t see any splitting in peaks. Worked fine for same sample in CD3CN
