✦ Synopsis

The underpotential deposition of Bi on Au has been investigated by specular reflectance spectroscopy and linear sweep voltammetry.

The spectral dependence of AR/R caused by Bi adatoms has been determined

and compared with the calculated spectrum.

A satisfactory agreement between experimental and calculated spectra was found. AR/R values have been used to determine the surface concentration of Bi,, which then has been used to calculate the electrosorption valence of Biad. It has been found that ysi = 2.6. The optical evidence of interaction of Bi ions with gold oxide has been obtained.
