The second feature is in fact the common peak for all 3 liquids, found for S OO (k) at k ≈ 3 Å-1 , and which would correspond to a distance r ≈ 2 Å, which is too small to represent any relative positions of the oxygen atoms whose size is close to 3 Å. In fact, this peak is a consequence of the OH charge ordering oscillations and should not given any other importance. The consequence of these two features, is that, when applied to S OO (k) of water, it demonstrates that the shoulder peak around k ≈ 2 Å-1 is in fact the OO contact peak, while the more apparent peak at k ≈ 3 Å-1 does not correspond to any relative oxygen atom positions, just like for the alcohols. But there is more, the main peak for water S OH (k) is equally positioned at k ≈ 2 Å-1 , suggesting an unphysical OH contact at r ≈ 3 Å, since it is too large than the expected r OH ≈ 2 Å. By analogy with the alcohols, it suggests that it could be a water pre-peak position, hence implying that the shoulder peak of S OO (k) is both the OO contact peak and pre-peak, which is a feature never suggested in the past literature of water.
