Abstract
The optical absorption associated with polarons and bipolarons in a tetrahedrally bonded homopolymer is studied within the Rice-Phillpot continuum model. Analytical expressions for the absorption coefficients are obtained and compared with those of polyenes. Both the intragap transitions involving the localized and extended states exhibit square-root singularities at their respective absorption edges.
