Molecular Structure of PANI. Figure 3 shows the FTIR
spectra of PANI deposited on conductive glass at different
potentials. It is clear that the characteristic peaks of polyaniline
(KBr, thin film, cm−1) present near the wavenumbers
of 1561 (C–C stretching mode for the quinoid ring), 1484
(benzenoid rings vibration), 1295 (C–N stretching mode),
