Abstract
Raman spectra of FeO, Fe 3 O 4 , α-Fe 2 O 3 , α-FeOOH, and γ-FeOOH, the common products of iron oxidation, have been measured. The spectra of FeO and Fe 3 O 4 appear to be identical. Armco iron oxidized in air at 250°C was examined by Raman spectroscopy after varying periods of exposure and the surface film was found to contain Fe 3 O 4 and α-Fe 2 O 3 .
