NMR problem
« on: February 03, 2009, 09:38:53 AM »
How to interpret the first four peaks (in R.H.S of HNMR) for the unknown compound (C16H14N2O2) containing 2 phenyl group, 2 carbonyl group generated from maleic acid anhydride and aniline?

For H NMR, I only know the peaks (10 H) for chemical shift around 7, but I cannot interpret the remaining 4H.

For 13 C NMR, definitely I only know the presence of CH2 in the compound, but not really give detailed information. Hope someone give some suggestions. Thanks.
