最近，几个小组，1-4已经使用超冷原子的光缔合来研究从自由原子到结合分子的跃迁。光缔合光谱学涉及用可调谐探测激光照射激光冷却和捕获的原子的集合。当探测激光器与跃迁到激发分子状态共振时，分子形成并通过电离分子或通过监测捕获原子数量的变化来检测。
Recently, several groups,1-4 have used photoassociation of ultracold atoms to study transitions from free atoms to bound molecules. Photoassociative spectroscopy involves illuminating a collection of laser cooled and trapped atoms with a tunable probe laser. When the probe laser is resonant with transition to an excited molecular state, molecules are formed and detected either by ionizing the molecules or by monitoring changes in the number of trapped atoms.
