论文摘要
我们描述了一项对YTTERBIUM单甲氧化物的激光光谱研究，YBOCH $ _3 $，这是一种使用激光冷却分子搜索时间反转对称性的感兴趣。我们报告了$ \ tilde {x} $和$ \ tilde {a} $状态的振动结构的测量值，$ \ tilde {a} $状态的几个组件的振动分支比以及低较低的电子状态的辐射寿命。 $ \ textIt {ab intib} $计算用于帮助分配振动发射带，并洞悉电子和振动结构。我们的结果表明，快速的光学循环对于yboch $ _3 $是可行的，为稳定阶命令的途径提高了P-和/或T侵入物理学的未来测量值的灵敏度。
We describe a laser spectroscopic study of ytterbium monomethoxide, YbOCH$_3$, a species of interest to searches for time-reversal symmetry violation using laser-cooled molecules. We report measurements of vibrational structure in the $\tilde{X}$ and $\tilde{A}$ states, vibrational branching ratios for several components of the $\tilde{A}$ state, and radiative lifetimes of low-lying electronic states. $\textit{Ab initio}$ calculations are used to aid the assignment of vibronic emission bands and provide insight into the electronic and vibrational structure. Our results demonstrate that rapid optical cycling is feasible for YbOCH$_3$, opening a path to orders-of-magnitude increased sensitivity in future measurements of P- and/or T-violating physics.
