Abstract

世界で初めて、溶液反応の超高速時間・角度分解光電子分光に成功 --溶液化学反応の機構解明に前進--. 京都大学プレスリリース. 2014-04-22.We present time- and angle-resolved photoemission spectroscopy of trapped electrons near liquid surfaces. Photoemission from the ground state of a hydrated electron at 260 nm is found to be isotropic, while anisotropic photoemission is observed for the excited states of 1,4-diazabicyclo[2,2,2]octane and I− in aqueous solutions. Our results indicate that surface and subsurface species create hydrated electrons in the bulk side. No signature of a surface-bound electron has been observed.
