摘要: Abstract A simple model of the coupling between a Frenkel exciton and charge transfer state is applied to study some consequences degeneracy intramolecular excitations for electroabsorption (EA) spectrum molecular crystal. It demonstrated that EA signal degenerate states need not follow first derivative absorption spectrum, as hitherto assumed. This invalidates one basic premises underlying numerical resolution spectra. The fullerene crystal discussed in new context.
