Аннотация:We have measured steady-state photoabsorption spectra of a soluble trans-polyacetylene, we have found that photoexcitation of the soluble polyacetylene transforms only into neutral solitons in the temperature range 85-300 K, with photoabsorption signals associated with charged solitons not observed. We consider the features of soliton excitations in comparison with other known types of polyacetylene. (13 References).
