Abstract :
We present the Resonance Raman Scattering spectra of highly conducting polyacetylene samples synthetized in different groups by using different methods: Shirakawa or S-(CH)x, Naarman or N-(CH)x and Tsukamoto or v-(CH)x. Different excitation wavelenghts have been used to study the different samples whose spectra have been then analyzed theoretically in the framework of the double distribution model. Results obtained by this analysis are discussed in relation with those carried out in NMR on the same films and with the values of the conductivity after iodine doping of these samples.
