| Outline of Final Research Achievements |
By developing extreme ultraviolet laser photoelectron spectroscopy of liquids, we have established a methodology for studying the electronic states and structures of molecules at gas-liquid interfaces. Technically, we increased the photon energy of the extreme ultraviolet laser light source and introduced a liquid film jet method, making it possible to observe even cations in solution. Furthermore, by comparing with molecular dynamics calculations, we explored the origin of the observed interfacial phenomena and at the same time verified the theoretical model.
