Abstract
Location of optical charge pairs formation in (alpha) -sexithienyl thin films has been determined by absorption and electroabsorption measurements carried out at 300 K and 4 K. The polarizabilities of the excited Frenkel exciton states have also been estimated. The exciton binding energy is in the order of 0.4 eV.
