| Outline of Final Research Achievements |
We developed ultrafast photoelectron spectroscopy to study chemical reactions in aqueous solutions. A liquid is discharged from a fused-silica capillary into a vacuum chamber and illuminated with the pump and probe femtosecond pulses. The pump pulse induces photochemical/photophysical dynamics and the probe pulse interrogates them by photoemission. We have studied the charge transfer to solvent reactions in water and found that photoemission from a hydrated electron is isotropic. Our analysis reveled that the solutes are hydrophobic and have enhanced concentration at the surface and they exhibit anisotropic photoemission; however, electron transfer occurs from these solutes to the bulk side of solution, so that the hydrated electrons are created with almost complete hydration shell. This makes photoemission from hydrated electrons isotropic owing to electron scattering with water molecules.
