What is an IR spectrum used to identify?
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms.
What would you look for in an infrared IR spectrum of methyl benzoate that would confirm its presence?
You should see the following peaks. It has a monosubstituted benzene ring, an ester group, and a methyl group. The strongest peak should be the ester C=O. The two strong bands arise from the symmetric and antisymmetric C-O stretches of the ester COO group, and the weaker band is the ether CO stretch of the OCH3 group.
