| 中文摘要 | ion clustering in aqueous solutions probed with vibrational energy transfer |
| 英文摘要 | despite prolonged scientific efforts to unravel the hydration structures of ions in water, many open questions remain, in particular concerning the existences and structures of ion clusters in 1:1 strong electrolyte aqueous solutions. a combined ultrafast 2d ir and pump/probe study through vibrational energy transfers directly observes ion clustering in aqueous solutions of liscn, nascn, kscn and csscn. in a near saturated kscn aqueous solution (water/kscn molar ratio - 2.4/1), 95% of the anions form ion clusters. diluting the solution results in fewer, smaller, and tighter clusters. cations have significant effects on cluster formation. a small cation results in smaller and fewer clusters. the vibrational energy transfer method holds promise for studying a wide variety of other fast short-range molecular interactions. |
