One can determine the skin bond length and shell thickness using the PDPS by equaling the fraction of the skin phonon abundance population to the volume ratio of a K-sized droplet (K = R/dH) , as described in Table . Fig. shows the PDPS distilled skin H-O phonon abundance, stiffness, and structure order, transiting from the bulk mode of 3150 cm -1 for ice and 3200 cm -1 for water to their skins. The skins of water and ice share the identical 3450 cm -1 that characterizes the supersolidity induced by molecular undercoordination. Surprisingly, neither ice-like cores liquid water nor liquidlike water covers ice, instead, both are wrapped by the common supersolid skin .
