You need to have some idea of what you might have, otherwise an IR sperctum isn't that useful. IR can gives you a clue as to what functional groups you have - but total structure elucidation from IR is, as Virgo would say, "A big ask".
It looks like you have an amide group, or maybe a conjugated carboxylic acid.
Do you know what reaction produced this product? have you got an NMR spectrum? MS data? anything else?
