The corresponding states in DQI T-27N-T and P-27N-P either have weak dipole-coupling to the ground state or weak contributions from configurations with direct CT (𝜏 !" = 952 ps/882 ps). We note that when the energetics of singlet fission are satisfied, the strength of the CT transition in the linear absorption spectrum is directly correlated to the magnitude of the SF rate constant and can be used to predict relative rates of triplet pair formation.
