论文摘要
用于测量电子偶极矩（EEDM）的极好的候选分子是单氟化th th thf $^+$），因为EEDM敏感状态为$^3Δ_1$，是电子基态，因此可免于自发衰减的腐蚀性。我们在$ x \，^3Δ_1$上进行光谱法，以提取对EEDM实验至关重要的三个光谱常数：超精细耦合常数，分子框架电偶极矩和磁性$ G $因素。为了了解热黑体辐射对振动基态的影响，我们研究了$ x \，^3Δ_1$的第一个激发振动歧管的寿命。我们从头开始计算，将它们与我们的结果进行比较，并讨论在Jila的新EEDM实验中使用THF $^+$的前景。
An excellent candidate molecule for the measurement of the electron's electric dipole moment (eEDM) is thorium monofluoride (ThF$^+$) because the eEDM-sensitive state, $^3Δ_1$, is the electronic ground state, and thus is immune to decoherence from spontaneous decay. We perform spectroscopy on $X\,^3Δ_1$ to extract three spectroscopic constants crucial to the eEDM experiment: the hyperfine coupling constant, the molecular frame electric dipole moment, and the magnetic $g$-factor. To understand the impact of thermal blackbody radiation on the vibrational ground state, we study the lifetime of the first excited vibrational manifold of $X\,^3Δ_1$. We perform ab initio calculations, compare them to our results, and discuss prospects for using ThF$^+$ in a new eEDM experiment at JILA.
