Having a terrible time identifying this IR spectrum
« on: December 09, 2012, 02:37:09 PM »

I know it is a carboxylic acid with a phenyl. The ar-oh should be an aromatic-OR.

It is very very difficult to identify a compound only from an IR spectrum. If the compound is known, then some spectrometers can attempt to match it with a spectral database. More information is needed unless someone happens to recognize this spectrum.

Do you think it could be 4-hydroxybenzoic acid?

Do you know a MW? Or elemental % composition?
