Characterization of four model systems. a polyphenylene oligomer, b cycloparaphenylene nanohoop, c branched phenylene ethynylene dendrimer, and d anthracene dimer (dithia-anthracenophane); Each panel contains the chemical structure, orbital plots of the transition densities for the two lowest excited states S2 and S1 (S3 and S2 in dendrimer) at the ground state equilibrium geometry, and the corresponding non-adiabatic coupling vector d12 (d23 in dendrimer)
