Fig. 6

Natural transition orbitals (NTOs) of the (a) twisted (M1) and (b) bent (M2) monomers and (c) the dimer formed from these two monomers. Here, E denotes the transition energy in eV, f represents the oscillator strength, λ is the eigenvalue of the NTO, and ∆µ signifies the dipole moment change in Debye for the S0 → S1 transition.
