| Research Abstract |
Time-resolved electrochemical slab optical waveguide spectroscopy utilizing ITO electrode with 1 msec time resolution was developed. The absorption spectral change from cytochrome c adsorbed on ITO electrode due to pulse potential step between oxidized and reduced form was observed every 2 msec. The time constant of electron transfer (ET) reaction between cytochrome c and ITO electrode was estimated to be about 10 msec from the fitting of the time- resolved intensity change in SOWG absorption spectra. Finally as a result of this study, ET rate constant (k) was evaluated to be 100 [s^<-1>].
