Fig. 3: Time evolution of the twist angle (τ) on the S1 state for P (blue) and M (red) enantiomers.

Cis-stilbene is shown in the upper panel (a) and cis-stiff-stilbene is in the lower panel (b). The bold line represents the weighted average of the total population over all the trajectory basis function (TBFs) on S1. Each line represents a TBF on S1, where the thickness of each line is proportional to its contribution to the weighted average.
