Today is maintenance day on BigSur, the CMLD-SCC NMR. I made two major upgrades:
#1) BigSur has a new workstation. I swapped the old workstation (which had a bad fan) for a brand new computer. As far as I can discern the configurations are the same, however let me know if you notice any odd behavior. The only difference you should be aware of is that you'll need to remap your network drives in order to access your data remotely. I synced the data with the old computer, so if you remap the drive you should be able to continue as if nothing changed.
#2) I swapped the probe. The old (BBO) probe could not be tuned properly on the 1H channel, leading to large(r) pulse widths, low(er) 1H signal-to-noise and less 1H decoupling bandwidth. I put a different probe (called a BBI) in the magnet. This probe will have slightly better 1H sensitivity at the cost of less 13C sensitivity. Hence, I would recommend considering sending any 13C-detected experiments to the cryoprobe via our courier service.
