How many peaks should be in DOSY spectrum of D2O sample?

How many peaks should be in DOSY spectrum of D2O sample?

Hello, I've recorded a DOSY data set and processed with Bayesian DOSY transform. There seem to be at least two peaks in the processed spectrum. Is the second one an artifact?

In theory there might be a signal of H2O along with HDO, but wouldn't exchange of deuterium be much faster than the experiment time scale?

Thanks.

[Question from NMRWiki Q&A forum] 2DNOESY with N15 C13 Labelled sample or Unlabelled sample 2DNOESY with N15 C13 Labelled sample or Unlabelled sample Dear Friends, I am in process of doing structure calculation of dimeric protein 22kD by using ARIA2.2 . Can I acquire 2DNOESY spectrum for my protein. Will it provide useful information for structure calculation? And whether I should acquire 2DNOESY with N15 C13 Labelled sample or Unlabelled sample . Which sample would be appropriate for this kind of experiment on VNMRJ 700 with biopack ?
