Fig. displays the droplet size and molecular site resolved electron lifetimes. The lifetimes of hydrated electrons increase with the drop of cluster size or the extent of supersolidity. The electron lives 100 ps longer and remains relatively stable in the skin than those within the droplets. The supersolidity of the NaBr hydration cell and the droplet skin slows down the dynamics of both phonons and the hydrated nonbonding electrons, in addition to the boundary reflection for the oscillating waves.
