19F NMR has some of the nicest looking spectra yet the example spectra on this page looks relatively ugly. I think a better example spectra would be a good idea. — Preceding unsigned comment added by 169.234.215.175 ( talk) 09:24, 21 August 2014 (UTC)

Is the 19F NMR really immune from NOE? I am not sure. — Preceding unsigned comment added by 149.132.102.139 ( talk) 17:36, 2 February 2012 (UTC)
It is my understanding that NOEs are the result of polarization transfer between nuclei. While I am not familiar with 19F NMR I would expect a proton-decoupled spectrum to exhibit enhancement much like normal 13C. Likewise a 19F equivalent of NOSEY type experiments should be possible. I suspect the statement in the article is false. NOE also operates through space and not through bonds so the commenting on bonding is at best a non sequitur.
This page features too much data describing very specific 19F chemical shifts. A simple, qualitative description of chemical shifts observed in fluorinated compounds discussing the trends one frequently observes in these shifts would serve this page far better. -- BASkeel ( talk) 22:36, 27 April 2020 (UTC)
