论文摘要
我们报告了畸形（I）苯氧化物（$ \ MATHRM {SROC} _6 \ MATHRM {H} _5 $或SROPH）的生产和光谱表征以及旨在抑制电子激发型在电子激发的振动期间振动激发的电子吸引力的电子吸引力的变体。根据理论预测，分散激光诱导的荧光光谱较高，这些物种的光学循环闭合是振动状态从自发光衰减而变化的脱钩。记录了高分辨率，旋转分辨的激光激发光谱，以估算光谱常数并鉴定候选的光学循环转变以进行未来的工作。结果证实了跨分子水平的激光冷却和量子态检测的苯氧化物氧化物的希望。
We report the production and spectroscopic characterization of strontium (I) phenoxide ($\mathrm{SrOC}_6\mathrm{H}_5$, or SrOPh) and variants featuring electron-withdrawing groups designed to suppress vibrational excitation during spontaneous emission from the electronically excited state. Optical cycling closure of these species, which is the decoupling of vibrational state changes from spontaneous optical decay, is found by dispersed laser-induced fluorescence spectroscopy to be high, in accordance with theoretical predictions. A high-resolution, rotationally-resolved laser excitation spectrum is recorded for SrOPh, allowing the estimation of spectroscopic constants and identification of candidate optical cycling transitions for future work. The results confirm the promise of strontium phenoxides for laser cooling and quantum state detection at the single-molecule level.
