Abstract

The formation of rates for singlet and triplet excitons associated with intermolecular charge-transfer process is computed. The calculation used the coupled cluster equation of motion approach. It is shown that the interchain bond-charge correlation has a strong influence on the relative ratio. The on-chain electron-electron correlation and electron-phonon coupling favor singlet exciton formation.
