The three-chromophore cycle system described in Eq. 19. One chromophore with D N h symmetry is excited with circularly polarized light (red circle) and is coupled with two of low-symmetry (a and b). (B) For two linear chromophores with different relative orientations with respect to the circular molecule, θ a ̸ = θ b , inverting the direction of the light will change the order at which an exciton initially localized at 1 populates the other two sites.
