摘要：

We offer a new interpretation of photoexcitations in trans-polyacetylene and polydiacetylene-4BCMU. Based on the results of picosecond photoinduced absorption and resonant Raman scattering, we postulate that breather excitons may be the primary species photogenerated in these, and perhaps, other conjugated polymers.
