Hi,

I have a molecule and an NMR spectrum, and I need to assign the NMR peaks to each of the carbons to the molecule.

I know that the 14.19 ppm and the 61.94 ppm correspond respectively to the carbon 12 and 11. However, I struggle for the other peaks especially between 116.76 and 148.51 ppm. I just know that it corresponds to the aromatic ring. Finally, I think that the 156.65 ppm and 155.15 ppm are respectively the carbon 9 and 10.

Thank you for your help.

I would use calculations of chemical shifts as well as the number of attached hydrogen atoms.

Exactly assigning all those signals is going to be impossible withtout further data comming from 2D experiments.
