Structural relaxation in supercooled water by time-resolved spectroscopy.

Author(s) : TORRE R., BARTOLINI P., RIGHINI R.

Type of article: Article

Summary

The authors report time-resolved optical Kerr effect measurements that unambiguously demonstrate that the structural relaxation of liquid and weakly supercooled water follows the behaviour predicted by simple mode-coupling theory. Their findings thus support the interpretation of the singularity as a purely dynamic transition. That is, the anomalous behaviour of weakly supercooled water can be explained using a fully dynamic model and without needing to invoke a thermodynamic origin. In this regard, water behaves like many other, normal molecular liquids that are fragile glass-formers.
