The photodynamics of the Ar-I2 complex and the formation of chemically bound argon

本项目的目的是研究碘分子(I2)在气相和氦纳米液滴中通过共价态和离子对的预解离动力学。纳秒和飞秒光电离化将与离子和电子成像相结合。此外，还将在分子束和He纳米液滴中研究I2与稀有气体(Rg)原子(Ar，Kr，Xe)和苯(C6H6)的络合物的光动力学。I2Rg络合物开辟了一条有效布居I2长程离子对态的途径，这有望在He纳米液滴中呈现出特别有趣的动力学特征。I2C6H6是光致电荷转移反应的典范，将首次在He纳米液滴中用飞秒泵浦探测光谱进行探测。

The goal of this project is to study the predissociation dynamics of molecular iodine (I2) via covalent and ion-pair states for I2 in the gas phase and in He nanodroplets. Both nanosecond and femtosecond photoionization will be employed in combination with ion and electron imaging. Fur-thermore, the photodynamics of complexes of I2 with rare gas (Rg) atoms (Ar, Kr, Xe) and with benzene (C6H6) will be studied both in a molecular beam and inside He nanodroplets. I2Rg com-plexes open a route to efficiently populating long-range ion pair states of I2, which are expected to feature particularly interesting dynamics in He nanodroplets. I2C6H6 is the paradigm for photo-induced charge transfer reactions which will be probed by femtosecond pump-probe spectroscopy in He nanodroplets for the first time.
