Abstract

Summary form only given. FT-IR and non-resonance FT-Raman spectra have been measured in three kinds of polyanilines (PANIs) chemically synthesized, i.e., leucoemeraldine base (LB), emeraldine base (EB) and pernigraniline base (PB) with different oxidation levels. In Raman spectra shown in Fig. 1, the peaks at about 1600 cm/sup -1/ and 1176 cm/sup -/ are attributed to benzenoid unit (B), while the peak at 1380 cm/sup -1/ are to benzenoid unit (Q). In IR spectra, we also observed several characteristic peaks in three PANIs, which are attributed to N-H stretching (3380 cm/sup -1/), C=C and C-C streching and bending modes (B : 1600, 1500, 1150 cm/sup -1/, Q : 1380, 1300 cm/sup -1/). The variations of oscillator strength at each IR and Raman peak among three PANIs are consistently interpreted in the viewpoint of the ratio of benzenoid and quinoid moieties.
