The resonance Raman spectra of poly(2,4-dichlorophenylacetylene) in the range of wavelengths of the exciting radiation between 457.9 and 647.1 nm were studied. It was shown that the frequencies, intensities, and shapes of the bands related to the backbone stretching vibrations changed as the frequency of the exciting light varied. This was explained by a rather broad distribution of the conjugated segments of the polymer over the number of conjugated C=C bonds. A possible structural model involving atrans-cis conformation of the chain of the polymer studied was proposed. |
