Abstract
The time dependence of photoinduced optical absorption in the prototype one-dimensional semiconductor, polyacetylene, is investigated with femtosecond resolution. It is found that the induced absorption appears in less than 150 fsec. The dynamics of the absorption decay are measured and compared with a model based on geminate recombination on a one-dimensional chain.Keywords
