Hello Everyone,

I'm desperate.

Please i need to draw a chemical structure for an unknown compound.I have carried our hnmr, cnmr, dept 135, dept 90 and hsqc on this compound.
I have tried assigning some groups to the results as can be seen on all the spectra, but my chemistry background is not strong,i am from a materials science background and this is as far as i can go. I am not really certain if i assigned the groups correctly.
The unknown compound is the product of the dissolution of an solid epoxy system in nitric acid.It is anticipated that the chemical structure of this compound should contain an aromatic or a benzene ring (the peak in the hnmr(2) sheet and the cnmr seems to confirm this).we also expect an end group like an OH group, a NH2 or NH-R, and maybe traces of nitric acid.
Any assistance will be highly appreciated. I really need to come up with a chemical structure for this compound.

Thank you so much.
