✦ Synopsis


Surface-enhanced second-harmanic signals are used to study sulfate ion adsorption during dectrolgtic cycling. The distinct differences between the spectral results obtained in K,SO, and H$Z04 can be attributed to the formation of silver oxide on the electrode surface. These investigations demonstmte the potential of second-harmonic generation ta study ionic adsorption at the electrochemical interface.

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

Enhanced Raman scattering has been observed from the hexacyanoferrate (II) and (III) ions adsorbed on Ag electrode surfaces. In the former case, five vibrational modes in the low-frequency range (214, 373,423,494 and 560 cm-') and four in the nitrilc-stretching region (2026,2067,2082 and 2122 cm-')

Optical second-harmonic generation from a fixed-frequency laser at 1= 1064 nm has been used to monitor the adsorption of sulfur atoms on a Pd( 100) single-crystal surface. The signal observed was dominated by the contribution from the adsorbate atoms to the second-order susceptibility due to a reson
