Ultrafast X-ray measurements of the glass-like, high-frequency stiffness of aqueous solutions

Abstract

The ultrafast dynamics of the domains surrounding solutes in aqueous solution have been measured by laser-generating GHz phonons inside of 30 mM ferrocyanide solutions and detecting the resulting molecular motions of the solutes and their hydrogen-bonded solvation shells using ultrafast X-ray absorption spectroscopy (UXAS). The measurements of the phonon dynamics around the solutes show that the domains have glass-like stiffness on tens of picoseconds timescale.
