The radial distributions of atom pairs in water and in solutions of hydrochloric acid have been measured by x-ray diffraction. The near-neighbor water correlations are strongly affected by the ions. Part of the experimental distributions is attributed to new oxygen-to-oxygen distances, associated with the presence of excess protons, and these distances become shorter as the concentration of the acid increases.
