Abstract

The surface enhanced Raman scattering (SERS) of interfacial pyridine and Br- species at Ag electrodes from neat pyridine solutions containing tetra-n-butylammonium bromide is presented. The potential dependence of the SERS peak frequencies, bandwidths, and relative intensities is reported and interpreted in terms of pyridine reorientation in the double layer. A band at 221 cm-1 is observed at certain potentials and is assigned to the AgN stretch for Ag surface pyridine species.
