Fig. 8. Time evolution of the reduced S₁ density along the bridge dihedrals during the first 2.5 ps of solution-phase AIMS dynamics. Average dihedral angles and S₁ populations were computed using 10° intervals, and linear interpolation was performed between these points. The percentages displayed in each panel represent the total S₁ population at the end of the specified time window, relative to their maximum at time = 0 fs. Gray dots indicate the dihedral angles of the fifty initial conditions.
