论文摘要
HD（$ 2-0 $）频段的P（1）线的饱和光谱测量在涉及频率梳校准的敏感腔体增强的光学设置中进行。频谱签名是羔羊峰的签名，与密度 - 矩阵模型描述一致，其中涉及9个超精细组件和16个交叉共振的$λ$ -type。实验光谱与仿真的比较得出的射击转变频率为209,784,242,007（20）kHz。在2 $σ$之内的非绝热量子电动力学框架中发现了一致性的一致性计算，其中合并的不确定性是由理论完全决定的。
A saturation spectroscopy measurement of the P(1) line of the ($2-0$) band in HD is performed in a sensitive cavity-enhanced optical setup involving frequency comb calibration. The spectral signature is that of a Lamb-peak, in agreement with a density-matrix model description involving 9 hyperfine components and 16 crossover resonances of $Λ$-type. Comparison of the experimental spectra with the simulations yields a rovibrational transition frequency at 209,784,242,007 (20) kHz. Agreement is found with a first principles calculation in the framework of non-adiabatic quantum electrodynamics within 2$σ$, where the combined uncertainty is fully determined by theory.
