Rearrangement of water molecules

The driving force for rearrangement of water molecules before instantaneous FC proton-electron charge transfer presents a problem. A five-molecule water superdipole assembly might acquire +25.9kT of thermal energy, but there will be a low probability that its subsequent rearrangement will direct it towards that for an intermediate state for FC electron transfer and proton discharge. This is not necessarily true for... [Pg.269]

Formation of a stable protein-DNA complex involves the rearrangement of water molecules and release of counter ions and water molecules to the bulk. Zewail and co-workers have used the time-resolved fluorescence up-conversion technique to explore the dynamics of the histone-DNA complex formation and the participation of hydration water in the stability and specificity of the recognition process [9]. This important study established the contribution from the entropic gain due to the release of hydration water (often termed dynamically ordered water) to the bulk. [Pg.170]

According to the solvophobic theory, the solvent cavity surface surrounding a hydrophobic moiety (Scheme 6) is similar to the water-vapor interface and thus the configurational rearrangement of water molecules at the interface does not propagate deep into the bulk water. In contrast. [Pg.116]

A considerably more strongly-bound partially embedded surface isomer. In this case, rearrangement of water molecules at the cluster surface has resulted in a partial solvation shell. [Pg.414]
