Abstract
We report on small-angle x-ray scattering measurements on liquid water aimed at characterizing the pressure evolution of its large-scale structure. Diffraction profiles have been fitted assuming a Lorentzian dependence on the exchanged momentum. As a result, we observe an anomalous behavior of the diffracted intensity that tends to disappear, increasing either the pressure or the temperature. This effect is discussed in detail and imputed to the ability of hydrostatic pressure to weaken hydrogen bonds.
