# Unusual triplet in 13C-NMR

Why is there a triplet at 46.7 ppm in the following spectrum of 2,2,2-tribromoethan-1-ol?

• The spectrum is of really poor quality. We can’t even see if the triplet is a $1:2:1$ or $1:1:1$ one. From the other (poor quality) spectra I can see on SciFinder, it looks as though that should be a singlet — but I can’t see too much on $75~\mathrm{MHz}$ spectra at that resolution. Finally, it seems weird that both signals should be of similar height even though one is quarternary and the other is secondary … – Jan Jun 20 '16 at 18:50
• I bet this is just a typo on the website. – jerepierre Jun 20 '16 at 22:39

• No, for some reason the website agrees that $46.7~\mathrm{ppm}$ is the $\ce{CBr3}$ group. Which would make sense if that is just a singlet. If you click on solution, it gives you the correct assignment. – Jan Jun 21 '16 at 20:43
