- How would you interpret this IR spectroscopy of 9-fluorenone? Some background information is that this was a lab to separate fluorene and 9-fluorenone. It should be noted that other solids and solvents used during the column chromatography was alumina, sand, petroleum ether, and dichloromethane. The original compound was 0.05 g but it yielded 0.03 g 9-fluorenone. There may or may not be impurities.Please help with determining the functional groups present in the IR data results of our isoamyl acetate sample.
