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.

该项目的目标是研究分子碘（I2）通过共价和离子对状态的气相和He nanodrops中的I2的预解离动力学。纳秒和飞秒光电离将与离子和电子成像结合使用。此外，I2与稀有气体（Rg）原子（Ar，Kr，Ar）和苯（C6H6）的络合物的光动力学将在分子束和He纳米液滴中进行研究。I2Rg复合物开辟了一条有效地填充I2的长程离子对状态的途径，预计这将在He纳米液滴中具有特别有趣的动力学。I2C6H6是光诱导电荷转移反应的范例，将首次在He纳米液滴中通过飞秒泵浦探测光谱进行探测。
