We decided that peak a would be on the sp₂ double bond Hydrogen because that is the approximate range expected for sp₂ Hydrogens. H_b was on an alcohol group, which means it would be downfield shifted as well. H_c is the bonded to the most highly substituted carbon, so it would be the next most downfield shifted peak. The rest of the Hydrogens were placed based on carbon substitution and proximity to double bonds/alcohol groups.

The assignment for the alcohol and adjacent Hydrogen could not be determined because there were no peaks in the expected range on the ¹H-NMR. Also, the Hydrogens given in the Experimental procedure totaled up to 26, but there were 28 expected Hydrogens on compound 4.
