本文提出了一种灵敏地测定激光诱导分子长程振动和转动能级频移的方法。该方案依赖于一个光学移频器，导致两个激光束具有精确和可调的频率间隔。一系列的光缔合光谱记录与两个光束诱导分子线，其峰分离提供了一个准确的频率标尺来测量铯分子水平的频率偏移，这还没有观察到在以前的报告。数据进行了比较，理论预测，并显示出良好的协议。
We experimentally present a technique for sensitively determining the laser-induced frequency shifts of the long-range molecular vibrational and rotational levels. The scheme relies on an optical frequency shifter, leading to two laser beams with a precise and adjustable frequency interval. A series of photoassociation spectra are recorded with both beams inducing molecular lines, whose peak separation provides an accurate frequency ruler to measure the frequency shifts of cesium molecular levels, which have not yet been observed in previous reports. The data are compared to theoretical predictions and show a good agreement.
