We investigate the effects of disorder on Frenkel excitons in disordered conjugated polymers. In these materials, the principal effect of the disorder is to modify the transfer integrals appearing in the exciton Hamiltonian by changing the angle of relative rotation between polymeric units in a random manner. It is assumed that the transfer integrals have the form tcos(ϕ k −ϕ k+1...
