Second harmonic generation (SHG) was employed to monitor in situ the potential-induced reconstruction of Au( 111) and Au( 100) electrodes. Rotating the sample by 360" about the surface normal yields for the unreconstructed Au( 1 I1 )-( 1 x 1) SWface the well-known threefold symmetry pattern in the S

The third-order susceptibility of a charged metal surface can strongly affect the efficiency for optical second harmonic generation from that metal. We present preliminary evidence for this effect on a polycrystalline Ni electrode probed at a fundamental wavelength of 1064 nm. The surface charge is
The rotational anisotropy in the optical second harmonic response from flat and stepped Ag electrode surfaces biased in an electrolyte solution have been examined. Compared to the flat Ag( 111) surface, the stepped surfaces show a pronounced effect due to the lowering of the surface symmetry. The re
