Explanation / Answer

After analysis of the IR spectrum of you, the following conclusions can be drawn.

The band at 3286.38 cm-1 belongs to the hydroxyl group. It corresponds to the O-H stretching frequency of the hydroxy group present in the molecule.

The bands 2998.16, 2982.67 and 2935.38 cm-1 belongs to the CH (aromatic), CH3 and CH groups which represent the C-H stretching frequency in this region.

The band at 1580.83  cm-1 stands for the aromatic ring C=C stretching present in the benzene ring having the nitro group together with hydroxy group n the alkyl chain connect at meta position.

The bands at 1521.99 and 1339.83 correspondence to N-O stretching frequency for asymmetric and symmetric stretching respectively.
