This molecule from your data that is not so much clearly shown but I can say this molecule could be benzyl acetate or ethyl benzoate as you have shown the peak of C=O and C-C and in nmr, we can see the presence of aromatic group very close to 6 ppm and between 8-9 the presence of carbonyl group. I am attaching the structures of compounds that seems possible for this type of spectra.
