在星际介质(ISM)中已经确凿地探测到了六个阴离子。他们都是在五年前结束的五年窗口内到达的。为什么没有检测到新的阴离子？这可能是因为缺乏关于新型阴离子的实验室数据。这项工作综述了价和偶极束缚激发态在ISM中可能观察到的阴离子的形成、检测和寿命中可能发挥的作用，以及量子化学如何加强这一理解。星际阴离子的清单肯定还没有用尽，但必须提供电子、光谱和结构数据，以帮助未来的任何探测。量子化学具有灵活性和完整性，可以提供这些系统的全貌，并在最近表现出了非凡的准确性。这里回顾的工作概述了量子化学计算已经产生并将继续提供的与阴离子有关的内容，以及这将如何加强实验室实验和天文观测。
Six anions have been conclusively detected in the interstellar medium (ISM). They all arrived within a five-year window ending five years ago. Why have no new anions been detected? It is likely a lack of laboratory data for novel anions. This work reviews the role that valence and dipole-bound excited states may play in the formation, detection, and lifetime of anions that may yet be observed in the ISM and how quantum chemistry enhances this understanding. The list of interstellar anions has certainly not been exhausted by any means, but electronic, spectroscopic, and structural data must be provided to aid in any future detections. Quantum chemistry has the flexibility and completeness to provide a full picture of these systems and has shown exceptional accuracies of late. The work reviewed herein gives an overview of what quantum chemical computations have produced and will continue to provide related to anions and how this will enhance both laboratory experiment and astronomical observation.
