IR Frequencies
The benzene ring helps produce the signal at about the 3030 range. While the C=C produce a strong signal at the 1450-1600 range.
The H-N-C=O is an amide group which has a signal appearing in the 3000-3500 range. A carbonyl group is producing a signal in the 1630-1690 range.
The N attached to 3 carbons is a tertiary amine, but since it is not connected to any H directly, it does not produce a signal in the 3200-3500 range like the other amines do. It produces the signal in the 1020-1360 range instead.
