论文摘要
天体物理分子光谱是通过探测质子与电子质量比（$μ$ $ $ $ $ $ $ $ $）来寻找新物理物质的重要手段。新的分子探针可以对$μ$的变化和新物理学理论的更好方向提供更严格的约束。在这里，我们总结了我们先前的论文\ citep {19symocu.cn}，以强调了峰值分子丰度和温度的准确估计以及电磁谱不同区域望远镜的光谱分辨率和灵敏度的重要性。虽然我们研究的11个天体性硅藻分子都没有显示出对天体物理环境的可观察到的强度敏感的旋转型转变，但我们对导致高灵敏度的因素有了更好的了解。从我们的结果来看，CN，CP，SIN和SIC表现出所有天体物理双原子分子的最有望进行进一步研究，目前正在对CN进行进一步的工作。
Astrophysical molecular spectroscopy is an important means of searching for new physics through probing the variation of the proton-to-electron mass ratio, $μ$. New molecular probes could provide tighter constraints on the variation of $μ$ and better direction for theories of new physics. Here we summarise our previous paper \citep{19SyMoCu.CN} for astronomers, highlighting the importance of accurate estimates of peak molecular abundance and temperature as well as spectral resolution and sensitivity of telescopes in different regions of the electromagnetic spectrum. Whilst none of the 11 astrophysical diatomic molecules we investigated showed enhanced sensitive rovibronic transitions at observable intensities for astrophysical environments, we have gained a better understanding of the factors that contribute to high sensitivities. From our results, CN, CP, SiN and SiC have shown the most promise of all astrophysical diatomic molecules for further investigation, with further work currently being done on CN.
