In order to better quantify the RET efficiency irrespective of light harvesting potential, we also report the final population of the sink state on MG relative to the maximum hole population of state |1 on the donor systems, which we denote Q D (1, 1) = 1ρ D (1, 1). The final sink population on MG divided by the maximum hole population on the donor is a rough estimate of the RET efficiency that is normalized for light-harvesting potential of the donor species. The quantity
