where |G⟩ is the electronic ground of the aggregate, ⃗ µ LE m and ⃗ m LE m are the transition dipole between |G⟩ and |LE m 1 ⟩. The implicit assumption in Eqs. ( ) and ( ) is that the transition dipoles for the CT states are zero, as these states are typically dark and influence the spectra in indirectly through their energy levels.
