Raman Spectrooscopic Study on The Electrochemmical Behaviours of Soluble Polyanine

In situ Raman spectra of souble PAn were taken to correlate its electrochemical reactions with structural changes.The pHdependence of Raman spectra and CV peak poisitions was observed.The reaction mechanism of three pairs of redox waves and the structures of PAn at various potentials were deduced, based on the spectral changes.
