Following the logic of analytic surface tension models, we have also linked the water structure with its interfacial thermodynamic properties. We have, for instance, shown that the more structured or ordered interfacial water layers (Figure ) correspond to smaller interfacial entropy contributions. As we have discussed in relation to Figure , the higher interfacial water entropies are observed on Ag and Pd which feature a modestly ordered water layer while smaller entropies correspond to either highly organized (Pt and Rh) or weakly ordered water (Au). Detailed entropy analysis also shows that the interfacial water layers have higher entropy than bulk wa-ter, probably due a disrupted hydrogen bonding network and the increased population of low-frequency translational water modes. Therefore, it is not enough to focus on the structure because the entropy arises mainly from the low-frequency modes of translation and rotation so consideration of water dynamics is crucial.
