Abstract
A mechanism for electroreflectance spectra formation is proposed for t he case of water adsorption with partial charge transfer on a nonunifo rm metal surface. This approach is based on an assumption of electromo dulation of optical polarizability in the adsorbed water layer. Linear and nonlinear potential dependences of spectroscopic characteristics of adsorbed molecules are discussed. The calculated electroreflectance spectra of iron agree well for weak partial charge transfer with the experimental spectra of active iron in 0.1 N NaOH.
