Phenol ftir spectrum
WebThe gap in the spectrum between 700 & 800 cm -1 is due to solvent (CCl 4) absorption. Further analysis (below) will show that this spectrum also indicates the presence of an aldehyde function, a phenolic hydroxyl and a substituted benzene ring. The inverted display of absorption, compared with UV-Visible spectra, is characteristic. WebAccess to this database is free of charge.
