Raman scattering of "Highly Conducfing" polyacetylene

Summary form only given. We present the Resonance Raman Scattering spectra of highly conducting polyacetylene samples synthetized by different methods: Shirakawa or S-(CH)/sub x/, Naarman or N-(CH)/sub x/ and Tsukamoto or v-(CH)/sub x/. The theoretical analysis of these spectra taken with different laser excitation wavelengths from /spl lambda/L = 1064 nm to /spl lambda/L = 457.9 nm is presented in the framework of the double distribution model. The results obtained by this analysis are discussed in relation with those of NMR carried out on the same films and with the values of the conductivity after iodine doping of the three different samples.
