Mössbauer spectroscopy has been used to study the structures of both the in situ and dried states of well‐passivated iron surfaces. The parameters found in this study correlate only with the parameters found in the literature for iron in amorphous iron (III) oxides and in polymeric chains. The same parameters determined for dried passive films correlate only with those of γ ‐ Fe 2 O 3 . The effects of drying the film give indications of the important role played by water in the passivation phenomenon.
