论文摘要
下面，使用泵送光电子成像的中性水簇中溶剂化电子的带隙形成与液体和液体和液体中的上述带隙激发研究的最新数据进行了比较。在簇和液体中，以200 fs和1-2 ps的顺序以200 fs和1-2 ps的方式取回类似的放松时间。放松时间与生成过程独立，表明这些时间由溶剂响应支配，溶剂反应比不同的溶剂化电子形成过程慢得多。对垂直电子结合能和电子结合能的时间演变的分析表明，溶剂化时间对结合能的依赖性。
Below band gap formation of solvated electrons in neutral water clusters using pump-probe photoelectron imaging is compared with recent data for liquid water and with above band gap excitation studies in the liquid and clusters. Similar relaxation times in the order of 200 fs and 1-2 ps are retrieved for below and above band gap excitation, in both clusters and liquid. The relaxation times independence from the generation process indicates that these times are dominated by the solvent response, which is significantly slower than the different solvated electron formation processes. The analysis of the temporal evolution of the vertical electron binding energy and the electron binding energy at half maximum suggests a dependence of the solvation time on the binding energy.
