Abstract
Photoinduced absorption measurements of poly (phenylene vinylene), PPV , made picoseconds after above-gap photon excitation, have been interp reted as showing that a majority of the photons create polaron pairs b ound by Coulomb attraction. We have calculated the peaks and approxima te widths of the absorption bands due to a polaron pair on adjacent ch ains in PPV, and find good agreement with the observed absorption.
