The results of this simulation are plotted in Fig. for excitation via right-hand or lefthand circularly polarized light, when the linear molecules a and b are oriented relative to the circular molecule according to θ a = 3π/4 and θ b = -0.6θ, respectively. We observe that the order in which the linear chromophores are populated by the exciton depends on the polarization of the light pulse. That is, the direction of circular polarization of the light determines whether the exciton rotates clockwise or anticlockwise around the cycle.
