Abstract

<p>Water is the most ubiquitous substance on earth and is known to have anomalous properties, which arise from the characteristic structure and dynamics of the hydrogen bond network in water. In this review, we focus on the dynamical aspects of water. Water dynamics is strongly controlled by the hydrogen bond network; there exist intermittent collective molecular motions associated with the rearrangement of the hydrogen bond network and concomitant fluctuation and relaxation in water. Five aspects of the water dynamics will be discussed: (1) intermittent collective motions and fluctuations with hydrogen bond network arrangements in water, (2) water properties at low and high temperatures, (3) molecular mechanism of water freezing, (4) role of water in biological systems, and (5) experimental methods for observing and analyzing the complex dynamics of water.</p>
