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