[Question from NMRWiki Q&A forum] Internal referencing in direct and indirect dimensions using guanidinium
Internal referencing in direct and indirect dimensions using guanidinium
Hello,
I am recording 15N-HSQC spectra of a protein in increasing concentrations (0.25–2.5 M) of guanidine hydrochloride. I would like to use the guanidine chemical shift (which appears in the HSQC) as an internal standard in both the direct and indirect (!) dimensions. My intuition is that the chemical shifts of guanidine should be independent of guanidine concentration. Does anyone know if this is really true?
Currently, I see a constant upfield shift in the indirect dimension, even for the guanidine peak...

[Question from NMRWiki Q&A forum] How to reference indirect dimensions in Topspin?
How to reference indirect dimensions in Topspin?
Hello, When I process 3d data on topspin with the ft3d command, I get the three-dimensional spectra, but the chemical shifts of the the indirect third dimension are not right (even though the sr parameter is correct) We do 3d ncc experiments on proteins (solid-state NMR). Anyone does 3d data processing on tospin and it actually works?
