there are two known mechanisms: friction heating( which may cause several degrees temperature increase) and induced AC current heating( in this paper:Electrical and ionic conductivity effects on magic-angle spinning nuclear magnetic resonance parameters of CuI. which can heat sample over 100 Celsius.)My question is, has any body seen this heating in MAS NMR?

[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 ?
Thanks & Regards Srinivas

sample not spining
HII am faceing spining problem on av-300 bruker instrument.I have change spinner,clean shim stack but the problem is still there have any body idea what i have do now,I have check by turning on and off spinner change spin rate but it not getting spinning.IS it electronic fault?

[Question from NMRWiki Q&A forum] 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.
