title: Comment on "A direct approach to study radiative emission from triplet excitations in molecular semiconductors and conjugated polymers" [J. Chem. Phys. 129, 041103 (2008)].
abstract: Comparison of the experimental radiative lifetimes of the lowest triplet (T(1)) state of aromatic hydrocarbons with the lifetimes calculated using spin-orbit interaction and time-dependent spin-orbit-photon interaction operators indicates that the traditional approach, based on spin-orbit interaction, yields much better agreement with experiment.
