标题： Sensitive Chiral Analysis via Microwave Three-wave Mixing

摘要： 我们在微波范围内展示了由手性引起的三波混频，使用1,2-丙二醇和1,3-丁二醇的冷气相样品的旋转跃迁。 我们表明，只能在手性环境中实现的体三波混频，能够敏感地、选择性地探测对映体过量，并适用于一大类分子。 双共振条件可以同时识别物质和手性，这应该允许在复杂混合物中进行灵敏的手性分析。 显示英文摘要

摘要： We demonstrate chirality-induced three-wave mixing in the microwave regime, using rotational transitions in cold gas-phase samples of 1,2-propanediol and 1,3-butanediol. We show that bulk three-wave mixing, which can only be realized in a chiral environment, provides a sensitive, species selective probe of enantiomeric excess and is applicable to a broad class of molecules. The doubly resonant condition provides simultaneous identification of species and of handedness, which should allow sensitive chiral analysis even within a complex mixture.
