Both papers deal with 17O NMR in large protein complexes, in solution and in solid state. New research approaches proposed by Gang Wu and his team have a potential to significantly advance the field of protein NMR spectroscopy.

[Question from NMRWiki Q&A forum] paramagnetic oxygen in solution NMR
paramagnetic oxygen in solution NMR
A student is running a kinetics experiment in a J-Young tube under 5-10 atm of oxygen, much like in this journal article:http://pubs.acs.org/doi/abs/10.1021/ja9061932
Student is seeing reduction in signal from his compound (slightly polar) and his internal standard (non-polar). Obviously paramagnetic oxygen?
The part I can't figure out: student is NOT seeing a reduction in his solvent peak. Solvent is benzene or toluene. I am assuming he is using at least some deuterated solvent.
I have found a lot of literature on the interaction of paramagnetic...
