While the total DoS distribution of the entire water film is rather similar across all the studied systems, the DoS for the first interfacial water layer (1WL) does depend on the underlying metal, as shown in Figure . The rotational DoS of the 1WL depends only slightly on the presence or the nature of the metal surface while the translation part is more sensitive. As the rotational frequencies remain unaffected, the rotational reorganization dynamics at the interface are also independent of the metal surface. For Au and Ag, the translational frequency retains its bulk value, while on Pt, Pd, and Rh, the band shifts to higher frequencies because of the higher local water density below 3 Å from the metal surface. Since the higher frequencies correspond to shorter velocity autocorrelation times, shifts in the DoS towards higher translational frequencies indicate faster translational reorganization of the interfacial water layer.
