Fig. 5. Potential energy scans around the minimum energy conical intersections obtained with QC1 of the S2 and S1 states (A and B) and S1 and S0 states (C and D). Panels A and C show the PESs calculated with QC1, while panels B and D illustrate NN potentials. See the caption of Fig. S7 in the ESI† for clarification of the dihedral angle.
