At larger coupling (A 0 = 0.05 a.u.), the descending polariton interacts with the lowest-energy polaritonic excited state (originally R 1 ) which then adds right-localized character to the Φ 2 state, effectively delocalizing the transition density across both arms. The NTOs are similarly perturbed showing the electron distribution delocalized while the hole distribution is only weakly delocalized at this coupling strength. As an additional analysis technique, the fragmented polaritonic transition density matrix can be found for both the |Φ 1 ⟩ and |Φ 2 ⟩ polaritonic excitations in Fig. at three values of coupling strength, which gives more information regarding the spatial coherence for each polaritonic excitation. 51 A similar analysis of the modifications to the |Φ 1 ⟩ transition can be found in Fig. showing that the R 1 state can be similar manipulated to show delocalized character at larger coupling strengths. At this point, the bright character of the R 1 exciton was transferred to the |Φ 2 ⟩ state.
