摘要：

The chemical structure of electrically conducting polypyrrole films has been studied for the first time by Fourier transform (FT)-Raman spectroscopy. The technique offers considerable signal-to-noise advantages over dispersive Raman spectroscopy and is useful for the analysis of weak scatterers including conducting polymers. Spectra of polypyrrole doped with p-toluene sulfonate and dodecyl sulfate are presented together with spectra obtained from the corresponding dedoped polymers. Samples were analysed in sealed glass containers and spectra obtained in 25 min. Analysis of the FT-Raman spectra shows them to be consistent with polaron and bipolaron descriptions of the electron transport mechanism in polypyrrole.
