The broadened peaks and shifts in the maxima can result from various changes in the the O-O-O or O-O dynamics, which can be addressed by analyzing differences between the 1WL and bulk water DoS. The overlain DoS in Figure shows that the translational maximum shifts to a lower fre- weaker than in bulk water and that the interfacial water would be looser and less organized than bulk water. On Ag, the O-O-O peak maximum is not affected by the surface but the O-O peak is shifted towards a lower frequency. These observations suggest that on silver the long-range interactions and ordering remain unaffected while the O-O interactions are slightly weakened and the 1WL would have less short-range ordering. On Pt, Pd, and Rh the shift in the peak maximum towards higher frequencies indicates stronger O-O-O interactions and increased long-range ordering. However, on Pd the O-O intensity is skewed towards lower frequencies, on Pt the O-O frequencies are slightly skewed towards higher fre-quencies while on Rh the O-O region is rather unchanged as compared to bulk water. These findings indicate that 1WL on Pd has less O-O correlation and hence less short-range order, on Pt the O-O interaction is slightly stronger while on Rh the short-range order does not not deviate from bulk water.
