摘要：

The adsorption of 4-cyanopyridine (PyCN) on Ag electrode has been studied by surface-enhanced Raman scattering. The Raman band of the CN group is at 2240 or 2100 cm-1; it appears in various ranges of potential. When a series of potentials was applied stepwise to the electrode, the growing and vanishing of both bands was monitored by an optical multichannel analyzer with a time resolution 1 s or less. Some information about the kinetics of the adsorption and desorption of CN group and about the adsorption geometry of PyCN on the electrode was obtained.
