| 摘 要： | The study of the adsorption properties and adsorption model of molecules or ions on substrates is an important part of surface enhanced Raman scattering (SERS) experimental investigations. In this paper, we will present the findings of our research work with regard to the potential dependence of the SERS spectra for 4, 4' -bipyridine (bpy) on the silver electrode and the adsorption model for bpy adsorbed on the silver electrode surface. We find the intensities of the SERS spectra with all Raman shifts can be changed by changing the applied potentiat and reach maxima when the applied potential is ca. -0.70 V (Vs. SCE). The experimental study also indicates that the pyridine ring of bpy adsorbs directly on the silver electrode surface via the N-atom.
