| Outline of Final Research Achievements |
The hydrated electron is an electron stabilized with the solvation in aqueous solutions by solvent water molecules. We generate electrons in the hydrophobic core of micelles by photoionization and observe the migration of the generated electrons to the outside water phase and the solvation process that follows the migration in the water phase with femtosecond time-resolved near-infrared absorption spectroscopy. Both cationic and anionic detergent molecules, sodium dodecyl sulfate and dodecyl trimethyl ammonium chloride, are used for the micelle formation. Recombination of the cation radical generated by the photoionization and the hydrated electron is delayed because the cation radical generated on the photoionization remains in the micelle core while the electron is solvated in the outside water phase.
