The investigation of hydrophobic hydration effects
The results of neutron scattering experiments on [CH 3] 4NCl (2 M), [C 4H 9] 4NCl (1 M) and [C 6H 5] 4PCl (0.3 M) aqueous solutions are presented. The generalised frequency distributions (GFD) for water molecules hydrating [C 4H 9] 4N + and [C 6H 5] 4P + ions were obtained from the neutron scatterin...

+ ions were obtained from the neutron scattering spectra. These data were compared with the results of ionic hydration previously obtained for LiCl (Novikov et al., Chem. Phys. Lett. 259 (1996) 391) and CsCl (Novikov et al., Physica B 234–236 (1997) 340) solutions. The comparison of GFD of hydration water molecules and GFD of pure water gives information concerning the ion influence on the rotation–vibration motions of surrounding water molecules and provides the data about changes in hydrogen-bounds network structure. The difference between the effects of ionic and hydrophobic hydration is discussed. |
