THE BIFURCATION REARRANGEMENT IN CYCLIC WATER CLUSTERS : BREAKING AND MAKING HYDROGEN BONDS

Tunneling patterns observed in the vibration–rotation–tunnelling spectrum of (H2O)5 measured near 2.7 THz established the time scale for bifurcation rearrangements to be approximately 40 ns. This relatively local process is likely to be relevant in the dynamics of liquid water and ice.
