Abstract
The relative contents of short and long conjugated chains in ethylene-acetylene copolymers (EAC) are determined by varying the lasing wavelength, as was done earlier for pure poly(acetylene). The Raman spectra of the copolymer samples doped with iodine contain the bands attributed to the iodine polyions I −3 and I −5 Unlike poly(acetylene), the ethylene-acetylene copolymer is characterized by the Raman spectra in which the intensities of the bands assigned to the I −5 polyions are higher than those of the I −3 polyions even at low degrees of doping. The structural features responsible for this difference are discussed.
