Abstract

In this study, the dynamics of the solvation of (Li+-electron) pairs were investigated in LiCl water solutions at concentrations from 2 to 14.6 M. The dynamics of contact pair solvation were observed for the first time experimentally using picosecond electron radiolysis. We observe a clear concentration-dependent increase in electron solvation time, from 10.6 ps at LiCl 3.5 M to 17.3 ps at 14.6 M. We discuss a descriptive mechanism of such a solvation in the presence of metal cations.

LiCl水溶液中电子-金属阳离子接触对的溶剂化动力学

在本研究中，研究了（Li+-电子）对在浓度为2 ~ 14.6 m的LiCl水溶液中的溶剂化动力学，并首次利用皮秒电子辐射实验观察了接触对溶剂化动力学。我们观察到电子溶剂化时间明显随浓度增加，从LiCl 3.5 M下的10.6 ps增加到14.6 M下的17.3 ps。我们讨论了在金属阳离子存在下这种溶剂化的描述机制。

期刊介绍： Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
