IR response of poly(o-toluidine): Spectral modifications upon redox state change

The IR spectra of poly(o-toluidine) in the reduced, half and fully oxidized states have been studied in both salt and base forms. The bands in the range 1500 to 1600 cm -1 undergo important intensity changes as the degree of oxidation increases. The IR spectra show that during the electrochemical po...
