    • If one takes into account the different directions of the ground-and excited-state dipoles, then the shift goes as the dot product of the ground-state dipole vector with the vector difference between the excited and ground states.

    • The interchain coupling of neighboring chromophores typically leads to a splitting of the ground and excited states, as described in: Cornil, J.; Beljonne, D.; dos Santos, D.A.; Calbert, Ph.; Brédas, J.-L. Thin Solid Films 2000, 363, 72-75. For the lowest-energy excited excimer state, we would expect the dipole moment to be near zero by symmetry.

    • We note that the parameters for the peak position and width of the reddest SRPL band centered near 730 nm were relatively insensitive to the details of the fit because of the band'S low amplitude.
