Abstract

The absorption spectra of polarons in polythiophene and solitons in polyacetylene are calculated using the VEH method. We point at the drawbacks of the widely used TLM model for some properties of the absorption spectra of these systems. The VEH results are shown to be in good agreement with experimental observations, in particular at points where the TLM model fail.
