            Hey all!
We've got a serious problem because with our new probe (5mm bbo bruker) the t1 noise in the heteronuclear corr...

            Hello All
Does anyone have any ideas on why the S/N would increase and then degrade during an HMBC-style experiment?  I...

            I'm trying to explain a missing HMBC peak, and having a coupling constant less than 10 Hz would do that nicely. It's a f...
