Forgive me, I feel like this is something I should know....
I've been working with a C6D6 sample today and about ½ the time it's
completely incorrectly referenced to the point that ½ of it is off the
scale. The samples are run on Bruker in ICON, yes, I'm selecting the correct
solvent... 🙂 Unfortunately, sometimes it happens during an HSQC
and it gets clipped due to the au program setting the sweep width.
1.
Why does this happen? I assume the referencing is set somehow during the lock,
so I guess it's locking on the wrong resonance?
2.
How can I prevent this?
