Abstract：In the present paper, surface enhanced Raman spectroscopy (SERS) was employed to study the interaction of 4,4’-bipyridine(BiPy) and Zn electrode. The results indicate that BiPy is adsorced with a vertical (or incline) orientation on the Zn electrode via one N atom of BiPy, and the two pyridine rings still remain on the same plane. BiPy has relatively stronger interaction with zinc metal than pyridine. The larger Raman scattering cross section and the existence of the two pyridine rings make it easy for 4,4’-BiPy to have stronger interaction with zinc metal.
