In the final part of our analysis, thermal effects on intra- and illustrate, we detect all key steps of intra-SF across the temperature range from 80 to 300 K, for both dimers. The lifetimes of (S1S0)rel, (S1S0)(T1T1) CT , and (T1T1) are in sound agreement with the TCSPC results. Notably, the lifetime of (S1S0)rel for mPhTc2 is temperature independent with a constant value of ca. 100 ps (Table ). For mAdTc2, however, the lifetime of (S1S0)rel increases from ca. 800 ps at We have explored two tetracene dimers that feature * rik.tykwinski@ualberta.ca
