Abstract
The polymerization of pyrrole adsorbed on a roughened gold electrode w as studied by surface enhanced Raman scattering (SERS) spectroscopy. I t was found that pyrrole was polymerized at -0.2 V vs. SCE and under o pen circuit. It is concluded that the polymerization of pyrrole occurs by the catalytic action of adatoms on a roughened gold electrode beca use pyrrole is adsorbed with the molecular ring parallel to the surfac e plane.
