Abstract

The photochemical reaction path approach and the CASPT2//CASSCF protocol have been employed to investigate the nonadiabatic photophysics and photochemistry of 2-thiouracil, with emphasis on the population of the lowest triplet state. Minimum energy structures, conical intersections, intersystem crossings, minimum energy paths, and spin-orbit couplings were discussed along the potential energy profiles, in order to investigate the efficiency of the nonadiabatic deactivation pathways from the initially populated state S2(1)(n(s)pi{*}), which can be useful to rationalize the absence of fluorescence and the population of the lowest triplet state.
