Photoelectron spectra of large size selected water cluster anions (H2O)n (n = 100–1100) have been measured at a low cluster temperature (80 K). An extensive peak analysis has been conducted in order to determine average and isomer-resolved vertical detachment energies (VDE) of the hydrated electron. This allows us, in combination with the reevaluated data of the previously reported results on small- and medium-sized water cluster anions ( J. Chem. Phys. 2009, 131, 144303), to draw a comprehensive picture of the size-dependent development of the VDEs of water clusters. This allows for an improved extrapolation of the cluster VDEs to the bulk, which yields a value of 3.60 ± 0.03 eV. The general size dependence of the VDEs is in very good agreement with a standard dielectric model.

大水团阴离子的光电子能谱

已在低簇温度 (80 K) 下测量了大尺寸选定水簇阴离子 (H 2 O) n ( n = 100–1100) 的光电子光谱。进行了广泛的峰分析,以确定水合电子的平均和异构体解析垂直脱离能 (VDE)。这使我们能够结合先前报告的中小型水簇阴离子结果的重新评估数据(J. Chem. Phys. 2009 , 131, 144303),以全面了解水簇 VDE 的大小依赖性发展。这允许将集群 VDE 外推到体,从而产生 3.60 ± 0.03 eV 的值。VDE 的一般尺寸依赖性与标准介电模型非常吻合。
