Further DFT computations on the skin effect of a unit cell containing 64 water molecules confirmed the expected relaxation of the segmental lengths and frequencies . The PDPS in Fig. and refine the skin effect on the HB vibration frequencies and lengths. The refinement reveals the abundance, stiffness, and structure order transition of the H-O bonds from bulk (B) to skin (S) and free radicals (R). The dH contracts from 1.00 to 0.95 and 0.92 Å, as the H-O transits from the bulk to the skin and the dangling radicals. The dL elongates from 1.67 to a broad range centered at 1.90 Å of high fluctuation. The O:H frequencies ωL turn out to be softer and the H-O frequencies ωH become stiffer.
