Fig. and show the effect of droplet polarization. Ultrafast pump-probe liquid-jet UPS measurements revealed that the bound energy of an electron hydrated inside the core interior of droplets is centered at 2.4 eV and 1.2 eV when located in the curved skin. The bound energy is 3.6 and 1.4 eV for an electron entrapped in the core and skin regions of a large volume of water. The bound energies drop with the (H2O)N -size till 0.4 eV for N = 5. The Eb drops linearly with the cluster size because of the undercoordination enhanced polarization. Because of the constant skin polarizability, the electron lifetime increases with the inverse of cluster size and remains constant in the skin. The cluster size dependency of the hydration electron bound energy and lifetime evidence the undercoordination enhanced polarizability of the droplets and skins. Likewise, the supersolidity slows phonon dynamics to raise the phonon lifetime from 2.6 ps to 50 ps for the 1.7 nm droplet . The supersolidity slows both the electronic and phonon dynamics.
