论文摘要
单羟化钙自由基（CAOH）是与凉爽恒星和岩石外球星的重要天体分子，以及其他天文学环境。 Here, we present a consistent set of highly accurate rovibronic (rotation-vibration-electronic) energy levels for the five lowest electronic states ($\tilde{X}\,^2Σ^+$, $\tilde{A}\,^2Π$, $\tilde{B}\,^2Σ^+$, $ \ tilde {c} \，^2δ$，$ \ tilde {d} \，^2σ^+$）的caoh。对该系统发表的光谱文献的全面分析允许从3204个Rovibronic实验过渡确定1955的能级，所有这些能量水平都具有独特的量子数标记和测量不确定性。该数据集涵盖了低于29 \，000〜cm $^{ - 1} $的分子状态的旋转激励最高$ j = 62.5 $。使用漫威算法进行分析，这是基于光谱网络理论的鲁棒过程。提供的数据集将大大帮助CAOH的未来星际，情节和大气检测，并协助设计有效的激光冷却方案在超低分子研究和基本物理学的精确测试中。
The calcium monohydroxide radical (CaOH) is an important astrophysical molecule relevant to cool stars and rocky exoplanets, amongst other astronomical environments. Here, we present a consistent set of highly accurate rovibronic (rotation-vibration-electronic) energy levels for the five lowest electronic states ($\tilde{X}\,^2Σ^+$, $\tilde{A}\,^2Π$, $\tilde{B}\,^2Σ^+$, $\tilde{C}\,^2Δ$, $\tilde{D}\,^2Σ^+$) of CaOH. A comprehensive analysis of the published spectroscopic literature on this system has allowed 1955 energy levels to be determined from 3204 rovibronic experimental transitions, all with unique quantum number labelling and measurement uncertainties. The dataset covers rotational excitation up to $J=62.5$ for molecular states below 29\,000~cm$^{-1}$. The analysis was performed using the MARVEL algorithm, which is a robust procedure based on the theory of spectroscopic networks. The dataset provided will significantly aid future interstellar, circumstellar and atmospheric detections of CaOH, as well as assisting in the design of efficient laser cooling schemes in ultracold molecule research and precision tests of fundamental physics.
