    As you already know that IR spectroscopy is performed to know the functional groups present in the given molecule. Therefore, if you know which functional groups are present then you can make a guess if options are given to you. But, if you have isomers having same functional groups then it's quite difficult to interpret the molecule. Kindly accept my answer!
