[Monitoring interfacial dynamics by pulsed laser techniques]. [Annual report, August 1, 1988--July 31, 1989]
Goal is the development and application of new optical methods to the study of dynamic processes at the electrode/electrolyte interface. The technique which was primarily focused on was second harmonic generation (SHG) because of its suitability for probing buried interfaces. A photothermal deflection spectroscopy station was also built for broad band study of the absorptivity of the interface. Dynamic processes initiated by either a fast potential step or a fast photoexcitation pulse was investigated. In the first case, metal/aqueous electrode systems were studied by time-resolved SHG. In the second, several photoactive materials of interest for solar energy devices were studied.
