). This provides compelling evidence that it is the LEF of the system that mediates the initial ET step, leading to the generation of RC, and subsequently, the reaction proceeds quickly. Does the LEF also regulate the R/S enantioselectivity? To probe the origins of the reaction's enantioselectivity, we computed the LEF along the y-axis for RC, TS1(R), and TS2(S) (see Table ). The LEF was found to be directed along positive y-axis for all the species. At the same time, the dipole moment for TS1(R) is aligned along the stabilizing direction vis-à-vis the LEF.
