| Description | Information regarding the dynamics of water molecules and small probes have been determined both is solution and complex environments such as supercooled liquids, room temperature ionic liquids has been gathered. A significant amount of instrument development has been undertaken in order to access very low temperatures using ultrafast 2D-IR spectroscopy using cryostats. This work has included a significant amount of understanding developed regarding the impact of such complex sample arrangements on data collected using ultrafast spectroscopy and the work is now beginning to bear fruit, with a PCCP publication in preparation. In addition the behaviour of water in complex biological environments has been studied with key roles for water in enzyme reactions uncovered. |
| Exploitation Route | Information has been recovered regarding the presence of a liquid-liquid phase transition in supercooled water. This is of fundamental interest to those studying hydrogen bonding in aqueous systems and could impact across the molecular physics and physical chemistry disciplines. |
