The fulvene molecule, which is a well-studied benchmark system within the nonadiabatic dynamics community, possesses a sloped S 0 /S 1 conical intersection along the methylene torsion coordinate that facilitates population transfer between the S 0 and S 1 surfaces after photo exciting to S 1 . In most studies of the conical intersections and nonadiabatic dynamics of fulvene, a multiconfigurational approach with at least the π system is employed, i.e. a CASSCF (6,6) wave function description. However, spin-flip TDDFT has also been employed to characterize the conical intersection, as well as TDDFT within the Tamm-Dancoff approximation (TDA) to explore the region of the potential around a conical intersection of fulvene as it rearranges to benzene. Here, we do not perform a detailed study of the nonadiabatic dynamics of fulvene, and so are not particularly concerned with the choice of electronic structure method and employ TD-CAM-B3LYP/6-31G(d) within the TDA to model the S 0 , S 1 , and S 2 states of fulvene in acetonitrile within the LSC approach.
