(Table ). For mPhTc2, the lifetimes of (S1S0)rel are 46.9 ps Importantly, the third fs-TAS species and the first ns-TAS species are both the intermediate state (S1S0)(T1T1) CT . The lifetime of (S1S0)(T1T1) CT is ca. 10 ns and is barely affected by solvent polarity and spacer (Table ). The second and third species share the same spectral signatures, that is ESA at 502 nm along with GSB at 535 nm for mPhTc2, and ESA at 523 nm as well as GSB at 550 nm for mAdTc2 in toluene. To Notably, the final step of intra-SF, that is (T1T1) decoherence to produce two independent triplet excited states (T1+T1), is observed in both strongly coupled mPhTc2
