If you set the default 1H experiment to be 8 scans (I reset to 16 every time, 32 if I have very little material), why is the default 13C set to 1024?!?! If you can get good 1H resolution in 8 scans you might not even need 256 for the 13C.

V. happy our latest paper looking at the potential for NMR active nuclei other than the proton in #metabolomics is out. Fantastic work all involved including third year project student Sophie Oakes. As a bonus it's #openaccess so everyone can read it.

Postdoc fellow opportunity in the group of Sheena Radford: https://jobs.leeds.ac.uk/vacancy.aspx?ref=FBSAS1057 Advertised as focused on #NMR in context of #amyloid formation. Deadline in March 2023. (Check the link!) #nmrchat

2 years after I started this project I finally resolved the quaternary carbons in the 13C-NMR spectrum!

Apparently the answer was to run a UDEFT experiment/sequence (various manual changes to relaxation delay, acquisition time, number of transients, or picking a different substrate in the same series, etc did not work).

Now online in pre-proof status, at the journal #SSNMR : a new collaborative paper on #DNP ssNMR at 13C natural abundance: "Fast magic angle spinning for the characterization of milligram quantities of organic and biological solids at natural isotopic abundance by 13C–13C correlation DNP-enhanced #NMR" . With Gaël De Paëpe, Snorri Sigurdsson and Sabine Hediger. Includes some new data of unlabeled #polyQ #amyloid aggregates. https://www.sciencedirect.com/science/article/pii/S0926204022000790 #nmrchat

"Aromatic ring flips in differently packed ubiquitin protein crystals from MAS #NMR and MD" by @schandalab - a nice new paper on probing #dynamics by ssNMR. https://doi.org/10.1016/j.yjsbx.2022.100079 in the Journal of Structural Biology X - special issue on solid-state #NMR ( #ssNMR #NMRchat )

@DNPFred Thank you! I hope the #NMRchat will be a great place to talk about magnetic resonance.
