论文摘要
最近的两篇文章提出了据称排除紫外光光谱中水合电子的多模式分布的结果。第一篇文章以这样的假设为基础,即以前在液态水中为溶剂化电子检索的非高斯真正的带状形状是由于检索中使用的电子散射横截面不足而产生的。第二篇文章不包括基于单个紫外光子能量记录的水簇中的溶剂化电子光谱谱的多模式带形状,它进一步假设簇结果可以在没有进一步合理的情况下转移到液体中。在这里,我们表明,基于当前数据,不能明确排除多模式分布。此外,基于当前可用的实验性紫外光谱光谱,群集结果向液体的转移性既不能被证明也不能被驳斥。
Two recent articles present results that allegedly exclude a possible multimodal distribution of the hydrated electron in ultraviolet photoelectron spectra. The first article bases its conclusion on the assumption that the non-Gaussian genuine band shape previously retrieved for the solvated electron in liquid water is an artefact arising from insufficient electron scattering cross sections used in the retrieval. The second article excludes a multimodal band shape based on a photoelectron spectrum of the solvated electron in water clusters recorded at a single ultraviolet photon energy, and it further assumes that cluster results are transferable to the liquid without further justification. Here, we show that based on current data multimodal distributions cannot be unambiguously excluded. Furthermore, the transferability of cluster results to the liquid can neither be justified nor refuted on the basis of currently available experimental ultraviolet photoelectron spectra.
