(A) A few best fits of the bulk fluorescence spectrum. The experimental spectrum is an average over time and measured complexes. Model parameter sets corresponding to different calculated spectra are {T = 9, ΔE = 160 cm⁻¹, λ = 220 cm⁻¹}, {T = 0.5, ΔE = 200 cm⁻¹, λ = 380 cm⁻¹}, {T = 0.5, ΔE = 220 cm⁻¹, λ = 340 cm⁻¹}, {T = 0.33, ΔE = 260 cm⁻¹, λ = 380 cm⁻¹}, and {T = 0.1, ΔE = 360 cm⁻¹, λ = 400 cm⁻¹}. (B) The T (transition rate ratio) dependence of an additional shift, δE, of all excitonic energies, which is introduced for a better fit. This shift is weakly dependent on λ and ΔE.
