抄録

The Raman spectra of a polyacetylene film doped heavily with SO₃ have been measured with excitation wavelengths between 488.0 and 1064 nm. Observed Raman bands are attributed to positively charged domains generated by SO₃ doping. Doping-induced changes in the Raman spectra are summarized as follows. (1) The ν₁ and ν₃ bands observed in the region of 1575-1485 and 1147-1112 cm^-1, respectively, upshift upon doping. (2) The ν₁ and ν₃ bands become broad upon doping. (3) Small but significant upshifts of the ν₂ band in the region of 1301-1294 cm^-1 are observed upon p-type doping in contrast to downshifts for n-type doping.
