The translational DoS of the 1WL slightly differ from the bulk water by the shape and maximum position while the maximum intensity is largely unaffected. In particular, the two bands corresponding to intermolecular O-O-O and O-O motions in bulk water cannot be distinguished at the interfaces, where only a single broad band is observed. Figure shows that on Au the translation peak maximum is slightly shifted to lower frequencies while on Ag the peak position remains unchanged as compared to bulk water. On Pd, Pt, and Rh the translational peak is shifted to slightly higher frequencies when compared to bulk water.
