The Interplay between ππ*/nπ* excited states in gas-phase thymine: A quantum dynamical study
A quantum mechanical study of the interplay between the bright ππ* (Sπ) and the dark nπ* (Sn) excited states of thymine in the gas phase is reported. TD-PBE0 calculations indicate that within a relevant region of the Sπ surface, connecting the Franck-Condon point with the planar and non-planar S π plateau, Sπ and Sn are almost isoenergetic and that a Sπ→Sn population transfer is therefore likely. This latter process has been studied by two complementary quantum dynamical approaches, a three-dimensional anharmonic (quartic) model, and a full-dimensional harmonic linear vibronic coupling model. Although providing slightly different quantitative indications, both approaches predict a very fast and effective Sπ→Sn population transfer: already at 50 fs the Sn state is significantly populated (20-40 %) and this population persists or even increases on a longer time scale. Walking the line: A quantum mechanical study of the interplay between the bright ππ* (Sπ) and the dark nπ* (Sn) excited states of thymine (see picture) in the gas phase is reported. The process is studied by two complementary quantum dynamical approaches, a three-dimensional anharmonic (quartic) model, and a full-dimensional harmonic linear vibronic coupling model.
