Abstract

Raman scattering experiments were performed on pristine trans-polyacetylene, on polymer samples where defects had been accomodated systematically along the chains, and on polydiacetylene. The results show that the dispersion of the satellite line strongly depends on the concentration of the defects. A calculation showed the sp3 carbons to be the most effective interruptions of the conjugation. Other physical and chemical properties like electrochemical doping, linewidth of e.s.r. signals and conductivity after doping are strongly related to the dispersion.
