We report on the application of Second Harmonic Generation (SHG) to in
-situ studies of the influence of bromide and pyridine adsorption on s
urface reconstruction of Au(111) electrodes (Au(111)-(square-root 3 x
23)), and on the potential induced reorientation of adsorbed pyridine
molecules. In the latter case a phase transition in the adsorbate laye
r has been observed which is accompanied by a significant phase shift
of the emitted SHG wave, indicating changes of surface electronic leve
ls upon adsorption of pyridine.
