In a similar fashion as for the fulvene molecule, in Fig. we present a closer look at the nuclear dynamics of 1,2dithiane for the spin-LSC approach as well as quantities from a single-trajectory. Fig. shows the density of the S-S bond length across 200 trajectories at an extended time scale of 500 fs. Note that Fig. only showed results up to 100 fs due to the limited AIMS data and with 1000 trajectories. In contrast to the C-C bond length density shown in Fig. , the S-S bond breaks and allows the nuclear wavepacket to broaden due to the larger conformational space. The potential energies of a single trajectory are shown in Fig. and clearly showcase the extended degeneracy of the ground and first excited states, starting from ∼30 fs until ∼300 fs when the S-S bond is reforming (see single-trajectory S-S bond length in Fig. ). The population of the excited state is shown in Fig. along with the coherences in Fig. . The population varies rapidly between the ground and excited state during the regions of degeneracy (30-300 fs) and implies that, unlike the fulvene molecule, trajectory averaging is required for the 1,2-dithiane system in order to make any prediction regarding the populations due to the immense and prolonged coupling between the states. Similarly, the coherence showcases equally complicated behavior in the regions of degeneracy.
