N2 - Effects of ions on the structure of water and the research work done on the topic is studied. A paper by Omta, Bakker, and colleagues in 2003, titled, 'Negligible effects of ions on the hydrogen bond structure in liquid water' was published in Science, a high-impact journal. This conclusion, pertaining to the reorientation dynamics of water molecules outside the first hydration shell of the ions studied, based on femtosecond pump-probe spectroscopy. The macroscopic water structure effects of ions noted in dilute solutions, from dynamic studies such as viscosity, NMR relaxation, diffusion, and thermodynamic ones such as entropy of hydration, transfer between light and heavy water, pertain to infinite dilution and, hence, concern the water outside the hydration shells. A paper by Vchirawongkwin and coworkers, employing quantum mechanical/molecular mechanical simulation with 499 water molecules per TI+ ion, demonstrates that water structure breaking is a very real process in dilute aqueous solutions.
