(A) Contour plot of the nsTA data of TDI₂ in 5CB collected at 345 mT, λ_ex = 685 nm. Data near 685 nm are omitted due to pump scatter. (B) TDI triplet-state EPR spectrum of TDI-PdTPP in butyronitrile at 105 K, λ_ex = 660 nm. (C) Contour plot of the TREPR spectra (X band) of TDI₂ in 5CB collected at room temperature, λ_ex = 660 nm, and (D) its corresponding EAS obtained using procedures discussed in the text. The dominant absorptive and emissive transitions have been assigned where Q_m and T_m refer to the ⁵(T₁T₁), m_s = m and T₁, m_s = m sublevels, respectively.
