| 英文摘要 | Water and electrolyte aqueous solution interfaces play crucial roles in many processes of physics, chemistry, environment, and biology. People have attempted to understand the structure and dynamics of water and electrolyte aqueous solution interfaces for decades. Recently, both experimental and theoretical studies have proved that larger and more polarizable anions attend to accumulate at the interface and affect the interfacial water hydrogen bonding structure. In this review, we present recent progress of nonlinear optical spectroscopy studies on water and electrolyte aqueous solution interfaces with nonresonant second harmonic generation (SHG) and sum frequency generation vibrational spectroscopy (SFG-VS). First, we addressed the signal source of the nonresonant second harmonic generation of the air/water interface. Analysis of the experimental results showed that the SHG signal of the air/water interface can be treated fully only with dipolar contribution, which lay the foundation of nonresonant second harmonic generation in studying water and electrolyte aqueous solution interfaces. We then utilized the polarization and molecular symmetry analyses to assign the SFG-VS spectra peaks to different interfacial species at the air/water interface. These results provide detailed informations on the orientation, structure, and dynamics of water molecules at the air/water interface. Subsequently, we studied several kinds of electrolyte aqueous solution interfaces by nonresonant SHG and SFG-VS. These results showed that not only the larger and more polarizable Br-anion, but also the smaller and less polarizable Cl-, F- anions are enriched at the air/water interface and increased the interfacial thickness. Furthermore, we also observed the specific Na+, K+ cation effect on the interfacial thickness and interfacial water hydrogen bonging structure. |
