报告摘要：

Understanding the electronic structure of molecules in the liquid phase is essential but poses experimental challenges. Soft X-ray spectroscopy can help effectively explore the electronic structure of matter. In this talk, I will share a summary of recent efforts at free-electron laser facilities, which have enabled liquid-phase soft X-ray spectroscopy to investigate the electronic structure of biochemical systems. Additionally, I will discuss the latest developments in table-top photon sources, including the first-time resolved measurement of multi-photon-induced dynamics in liquid alcohols using an HHG-based setup. Table-top soft X-ray (SXR) sources have made it possible to conduct time-resolved X-ray absorption spectroscopy (TRXAS) to study structural and electronic dynamics in real-time. By using long-wavelength driving pulses, it has become possible to extend high-order HHG cut-off and XAS measurements into the water-window. This spectral range spans between the carbon and oxygen K absorption edges and opens up the possibility of conducting TRXAS measurements in liquid samples and solutions.
