Abstract
Inelastic X-ray scattering experiments on sub- and supercritical water were performed to investigate collective dynamics of this unique solvent. Analysis within a generalized Langevin formalism shows that the positive dispersion of the inelastic excitations, as compared to the hydrodynamic value, first decreases (1.0 < Ï < 0.8 g cmâ3) at all measured momentum transfers, Q = 1.3-10.7 nmâ1, and then increases (0.7 < Ï < 0.26 g cmâ3) again only at higher Q. The latter increase may be related to a fast breaking and reforming of the hydrogen bonds in sub- and supercritical water.
