On the Intrinsic Population of the Lowest Triplet State of Thymine
... the computed electronic SOC is somewhat low, ∼2 cm-1, predicting a long lifetime and a slow relaxation for the triplet state, becoming therefore prone to react. In summary, by means of CASPT2//CASSCF calculations and by computing minimum-energy paths, minima, conical intersections, singlet-triple cr ...
