This is an IR spectrum of trans-chalcone using KBr plates. I can identify some of the peaks (listed below). But what are the other peaks below the 1600s? I don't know what else there is to identify. Also, are there different vibrations going on?
3084 is for the aromatic rings
1664 is for the ketone
1607 is for the alkene
