摘要

利用动态太赫兹克尔效应(TKE)研究了高电荷离子对液态水氢键网络局部结构变形的影响。通过对所选离子阴离子与阳离子电荷密度的系统变化，我们发现了离子电荷密度与水中旋转运动和平移运动之间耦合的增强或减弱之间的相关性。后一种分子间探针，清楚地显示了相反的阴离子与阳离子效应，使我们能够对离子的结构形成/破坏行为提供新的见解。

Intermolecular Probe for the Structural Deformation of Liquid Water Around Highly Charged Ions

We study the impact of highly charged ions on the local structural deformation of the hydrogen-bonding network of liquid water by means of dynamic Terahertz (THz) Kerr effect (TKE). By a systematic variation of anionic vs cationic charge density of the selected ions, we discover a correlation between the ionic charge density to the strengthening or weakening of the coupling between the rotational and the translational motions in water. The latter intermolecular probe, clearly shows opposite anionic versus cationic effect and enables us to provide a novel insight on the structure making / breaking behavior of ions.
