WebJul 22, 2010 · There is at least as much art as science to reading an FTIR. A used oil scan is pretty much useless unless it's compared to a reference scan of the unused oil. That way you can watch additives deplete, oxidation increase and gremlins creep in, if you know what you're looking for. WebJan 28, 2024 · The spectrum for 1-octene shows two peaks that are characteristic of alkenes: the one at 1642 cm -1 is due to stretching of the carbon-carbon double bond, and the one at 3079 cm-1 is due to stretching of the s bond between the alkene carbons and their attached hydrogens.
