N2 - In this study, polypyrrole (PPy) films were electropolymerized under different preparation conditions on rough gold substrates. The peak shown at the higher frequency of the double peaks at about 1329 and 1386 cm-1 in surface-enhanced Raman scattering of PPy was initially assigned to the ring stretching of oxidized PPy. A systematic study was carried out to confirm this assignment. It was found that the conductivity of PPy was strongly related to and increased with this Raman peak intensity of oxidized PPy. Meanwhile, the normalized relative intensities of this Raman peak for various PPy films are consistent with their corresponding doping levels.
