我们提出了时间和角度分辨的光电子能谱的液体表面附近的被困电子。水化电子基态在260 nm处的光电子发射是各向同性的，而1，4-二氮杂双环[2，2，2]辛烷和水溶液的激发态光电子发射是各向异性的.我们的研究结果表明，表面和次表面的物种在体侧产生水合电子。没有观察到表面束缚电子的特征。
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 andin 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.
