Metastable molecules, such as super-excited Rydberg and non-valence bound states, may emit electrons through electron-electron or electron-vibrational coupling. The structural shifts following emission reflect electron-nuclear coupling, revealing how electronic movement induces structural change. Using ultrafast lasers, we detect these emitted electrons to track real-time molecular transformations. 

Inhomogeneous solvation can significantly alter reaction pathways and kinetics compared to those observed in isolated gas-phase or fully solvated bulk environments. Focusing on micro-hydrated systems with shallow solvation shells and asymmetric solvation at air/water interfaces, we track electron dynamics to determine how these specific environments diverge from traditional benchmarks. 

Detecting electrons across diverse environments remains one of the most significant challenges in spectroscopy. We address this by developing and applying novel methods, such as High-harmonic spectroscopy (HHS) and Time-resolved photoelectron spectroscopy (TRPES) using liquid microjets. Driven by ultrafast, high-energy VUV and XUV laser systems, our work aims to extend these techniques into the solid phase, enabling the study of electron dynamics across a broad range of functional materials.
