The flickering cluster model of liquid water. A given water molecule (circled) is (o) in the middle of a cluster at time ti, (b) at the edge of a different cluster at time fj, and (c) free at time The various water molecules are shown relatively stationary in space from one moment to another. In reality, each would move (translate and rotate) more than is shown here.

In Figure 1.5b the Frank-Wen flickering cluster model envisions larger clusters of H-bonded water surrounded by noncluster waters, which nonetheless interact with neighbors by dipole-dipole forces. The lifetime of the clusters is estimated at around 100 picoseconds (ps), which is long with respect to the... 

With reference to Figure 11.5 showing the involvement of a given water molecule in the liquid, write a short paragraph describing what is meant by the phrase flickering cluster model as applied to the structure of liquid water.
