Triplet exciton energy and the magnitude of the charge-transfer interaction inside dimers in the Alkali-TCNQ salts

Abstract

The optical absorption spectra of several crystalline anion radiacal salts have been analyzed recently within the frame of the model Hamiltonian of electrons and intramolecular excitons and vibrations in the limit of strong interaction of the excitonic and vibrational motions with the unpaired electrons. In the present work the magnitude of the intermolecular charge transfer interaction inside dimers in the Alkali TCNQ salts is deduced from the knowledge of the experimental triplet exciton energy and the constants characterizing the electronic, excitonic and vibrational properties of TCNQ molecules. Perturbation calculation is used to derive a formula for the triplet exciton energy.
