HNCB Triple Resonance Experiment (Varian)

Hello,

Has anyone come across this experiment? I see it listed but have not been able to find the pulse sequence. I have noticed that in some cases that the reference simply implies the HNCACB experiment running in such a way to allow complete transfer to the CB.

So is there an HNCB or is the only HNCB in the form of the HNCACB with the delay set to allow complete transfer to the CB?

Thanks in advance!!!

[Question from NMRWiki Q&A forum] From what experiment only two bond correlations we can get in varian nmr? From what experiment only two bond correlations we can get in varian nmr? Hi., i have one compound i need only two bond correlation contours from quaternary carbon to proton. Is there any pulse sequence to find only two bond correlations ie, from quaternary carbon to protons with minimum amount of sample in "varian nmr". Check if somebody has answered this question on NMRWiki QA forum	nmrlearner	News from other NMR forums	0	12-28-2010 05:27 AM
