Femtosecond Photoelectron Spectroscopy of Molecular and Cluster Anions

加州伯克利大学的丹尼尔·纽马克教授在实验物理化学项目的支持下，对分子和团簇阴离子的时间分辨动力学进行了实验研究。 该工作的目标之一是了解溶剂化阴离子的气相和溶液解离动力学的显着差异，特别注意过量电子的影响。该工作继续使用飞秒光电子能谱进行研究，还将包括对光电子角分布的新研究。对团簇中阴离子的基础研究将有助于深入了解这些物种的溶剂化，这在电化学和生物化学过程以及化学合成中具有重要意义。 了解当过程从气相转移到溶液相时反应性发生的变化将使我们能够更好地利用冷凝相应用中数十年的气相数据，大多数工业应用都发生在冷凝相。

Professor Daniel Neumark of University of California Berkeley is supported by the Experimental Physical Chemistry program to perform experimental studies on time resolved dynamics in molecular and cluster anions. One of the goals of the work is to understand the significant differences in the gas phase and solution dissociation dynamics of solvated anions, paying particular attention to the effects of the excess electron. The work continues studies using femtosecond photoelectron spectroscopy and also will include new investigations into photoelectron angular distributions. The fundamental study of anions in clusters will lead to insights about solvation of these species, which are of great importance in electrochemical and biochemical processes, as well as in chemical synthesis. Understanding the changes that occur in reactivity when a process is transferred from the gas to the solution phases will allow us to better utilize decades of gas phase data in applications in the condensed phase, where most industrial applications occur.
