Abstract

In the present contribution we summarize our observations concerning the ultrafast non-equilibrium dynamics of water, in both the liquid and crystalline phase. Our experimental tool is two-dimensional infrared (2D IR) spectroscopy, which combines structural information on a molecular level with femtosecond time resolution. In the case of liquid and supercooled water we are able to extract the timescales of hydrogen bonding dynamics, whereas in the ice form we can probe the change of the hydrogen bond properties under excitation and observe the influence of intermolecular mode excitations in the crystal.
