Water is unique in its number of unusual, often called anomalous, properties. When hot it is
a normal simple liquid; however, close to ambient temperatures properties, such as the …

We present an overview of recent static and time-resolved vibrational spectroscopic studies
of liquid water from ambient conditions to the supercooled state, as well as of crystalline and …

Water is the most abundant liquid on earth and also the substance with the largest number
of anomalies in its properties. It is a prerequisite for life and as such a most important subject …

Water is a complex liquid that displays a surprising array of unusual properties, the most
famous being the density maximum at about 4° C. The origin of these anomalies is still a …

The origin of water's anomalies has been a matter of long-standing debate. A two-state
model, dating back to Röntgen, relies on the dynamical coexistence of two types of local …

The viscosity of a liquid measures its resistance to flow, with consequences for hydraulic
machinery, locomotion of microorganisms, and flow of blood in vessels and sap in trees …

Liquids can be broadly classified into two categories, fragile and strong ones, depending on
how their dynamical properties change with temperature. The dynamics of a strong liquid …

Water shows intriguing thermodynamic and dynamic anomalies in the supercooled liquid
state. One possible explanation of the origin of these anomalies lies in the existence of a …

The fundamental properties of water molecules, such as their molecular polarizability, have
not yet been clarified. The hydrogen bond network is generally considered to play an …

We review the recent research on supercooled and glassy water, focusing on the possible
origins of its complex behavior. We stress the central role played by the strong directionality …
