Abstract
Photo-induced electronic and vibrational absorption of polydiacetylene (10H) in the infrared (400-4000 cm-1) is found to be consistent with photo-generation of bipolarons. Overlap of electronic and vibrational transitions occurs due to strong electron correlation effects which reduce the electronic transition energies. Electron-phonon interaction produces anti-resonances in the bipolaron electronic absorption.Keywords
