Local ordering of water

The tetrahedral arrangement that characterizes the local ordering of water molecules in the V structure dissipates after about 10 s (at 283 K) because the nearest neighbors of a given molecule are relatively free to change their positions in response to thermal perturbations. This relaxation time is about one order of magnitude smaller than the time scale for diffusive translational and rotational motion of the molecules in liquid water at 283 K, as can be inferred from Table 2.2. The physical meaning of...
