我们提出了第一个振动分辨电子光谱的孤立的银氢化物阳离子Ag 2 H+，这已被合成的多级质谱在四极离子阱。用作用光谱法测得了实验的光碎裂谱。高水平的从头计算模拟再现了实验结果，并提供了Ag 2 H+基态和激发态电子态的结构特性的精确分配，Ag 2 H+在重要的化学反应中充当中间体，如碳-碳偶联。
We present the first vibrationally resolved electronic spectrum for the isolated silver hydride cation Ag2H+, which has been synthesized by multistage mass spectrometry in a quadrupole ion trap. The experimental photofragmentation spectrum has been obtained by action spectroscopy. High-level ab initio simulations reproduce experimental findings and provide precise assignment of structural properties of ground and excited electronic states of Ag2H+, which serves as an intermediate in important chemical reactions such as carbon−carbon coupling.
