Hi all,
I was hoping someone would be able to turn me in the right direction for
looking at 13C-2H correlations in solution-state.
This is what we see separately:
The (1D 1H-decoupled) 13C spectrum has several regions of resolved singlets.
The (1D 1H-decoupled) 2H spectrum has a single broad peak (20Hz at half-width).
I would like to select/identify the 13C peaks directly bonded to a 2H.
Does anyone have a reference?
-------------------------------------------
I know of a solid-state recoupling experiment using xyxyx composite pulses in
place of REDOR pi-pulses (JMR 145:52(2000)), but I'd like to work in the
solution-state.
Only thing I can think to try at this stage would be to try to transfer
magnetization between carbon and 2H with a spin-lock and looking at the
difference spectrum without magnetization transfer (1D)?
I don't think 2D would be worth it since there's only one 2H peak . . .
Has anyone succesfully used through-bond transfer between spin-1 and spin-1/2?
All ideas are most welcome.
Thank you for reading this far.
Cheers,
Yael
