What possible advantage does IR have over NMR spectroscopy? IR may show functional groups more clearly than NMR Less sample is needed for IR than for NMR IR may be done on gaseous samples whereas NMR cannot IR may be done at room temperature whereas NMR cannot Question 2 Where can integration values be found on NMR spectra? It may vary depending on the processing software used At the bottom of each peak, with a bracket At the top of each peak, accompanied by an integration curve On either the left or right side of each peak
