摘要：

In situ Raman and reflectance spectra of iron electrodes in borate buffer pH 8.4 containing 2,2'-bipyridine (bipy) have been investigated. In the potential range where Fe(OH)2 is expected to be formed the in situ Raman and reflectance spectra were identical to the resonance-enhanced Raman and absorption spectra of the [Fe(bipy)3]2+ Complex, respectively. The results have shown that in the presence of bipy the equilibrium Fe(OH)2 half arrow right over half arrow left Fe2+ + 2 OH- is displaced to the right as a result of the formation of the [Fe(bipY)3]2+ complex.
