Help with interpreting 1H NMR and IR spectra

Postby GoGoGadget on December 7th, 2011, 12:50 pm 

Would anyone be able to tell me if I'm on the right track with determining the peaks on these NMR spectrums? We had to synthesize a product of Chalcone and then hydrogenate it to obtain an unknown product that we have to correctly identify. This had been quite a difficult spectrum for me to interpret and any input would be appreciated! For the IR spectrums, I think I have the right peaks determined and noticed that the carbonyl shift switches to a higher energy level in the hydrogenated spectrum from the chalcone spectrum. Is this due to resonance?
