Explain how IR spectroscopy could be used to confirm product formation. Refer to specific functional groups, provide characteristic IR band frequencies and indicate the type of vibration (i.e.. stretching vs. bending). In this experiment, NaOH is used as a base, to convert 5-nitrobenzisoxazole to 2-hydroxy-5-nitrobenzonitrile.
