1H - NMR spectra, some very strange peaks at 6 ppm
« on: March 25, 2020, 10:05:04 PM »
Hi all.
Currently working through some NMR. I got this spectra which has a strange cluster of peaks at 6. It looks like a double quintet but it doesn't have the shape that a quintet would usually have. Can anyone identify what this could be?
Also the compound is unknown (for now) and I assume it was dissolved in Deuterated Chlorofom.
Thanks for any *delete me* :)

Have you tried applying the rules of first-order multiplets?  There is an article on how to do this by Brian Mann at J. Chem. Ed. 1995 72(7) 614-615.

I those are two overlapping peaks. A doublet of triplets and a quintet. Pretty neat to see them so nicely resolved, is that a high field NMR?
