This project is focussed on the detection and characterization of ICD in aqueous solution. To this end we will use electron spectroscopy of a liquid microjet excited by synchrotron radiation, a technique which has been pioneered within this group. First results from liquid samples are indicating that direct transitions into delocalized two-hole states do take place in a liquid environment, and can be very effective. Unlike in some other projects within this Research Unit, in liquids and solvents the non-local decay amplitudes responsible for ICD have been addressed in the high-energetic decay of true core levels. Inner valence ICD is yet unproven in liquids. Demonstration of the latter is another goal of this project, and will be carried out in collaboration with the Hergenhahn group. Our work is planned to establish the dependence of ICD spectral shapes on solvent structure, which we see as an important future application of this process. This work will be done in close cooperation with theoreticians of the Dreuw group.

本项目主要研究水溶液中ICD的检测与表征。为此，我们将使用由同步辐射激发的液体微射流的电子能谱，这是本小组首创的技术。来自液体样品的第一个结果表明，在液体环境中，直接过渡到离域双孔状态确实发生了，并且非常有效。与本研究股的其他一些项目不同，在液体和溶剂中，引起ICD的非局部衰减幅度已在真堆芯能级的高能衰减中得到解决。内价ICD尚未在液体中得到证实。后者的演示是该项目的另一个目标，并将与Hergenhahn小组合作进行。我们的工作计划是建立ICD光谱形状对溶剂结构的依赖性，我们认为这是该工艺的一个重要的未来应用。这项工作将与德鲁小组的理论家密切合作。
