乙腈团簇阴离子（CH_3CN）（-）（n）（n=10-100）的阴离子光电子能谱成功地证明了两种不同阴离子物种的竞争共存：溶剂化电子和溶剂结合价阴离子。烧孔型光电子能谱和相对光剥离截面测量揭示了这些阴离子的明显不同的性质。这种不寻常的共存归因于它们的阴离子状态在溶剂分子的数量足以几乎完成第一溶剂化层时的紧密性质。
Anion photoelectron spectroscopy of acetonitrile cluster anions, (CH3CN)(-)(n) (n=10-100), successfully demonstrates the competitive coexistence of two different anionic species: a solvated electron and a solvent-bound valence anion. The distinctly different nature of these anions is revealed by hole-burning-type photoelectron spectroscopy and relative photodetachment cross section measurements. This unusual coexistence is attributed to the closely lying nature of their anionic states at just the number of solvent molecules sufficient to almost complete the first solvation layer.
