我们证明了三波混频的对映体分化在微波制度中使用的旋转转换在冷气相样品的薄荷酮和香芹酮。该技术也可以被理解为偏振依赖的双共振实验，最近已被证明具有高的手性灵敏度和混合物的兼容性，由于其共振特性。在这里，我们将其应用于含有两个立体中心的分子，研究更复杂的物种的重要一步。我们还证明了同时微波三波混频的两个结构相关的单萜，薄荷酮和香芹酮，在手性混合物中，这是可能的，由于旋转光谱的结构差异的高灵敏度。
We demonstrate three-wave mixing for enantiomer differentiation in the microwave regime using rotational transitions in cold gas-phase samples of menthone and carvone. The technique can also be understood as a polarization-dependent double-resonance experiment and has recently been shown to have high chiral sensitivity and mixture compatibility due to its resonant character. We here apply it to molecules containing two stereogenic centers, an important step towards investigating more complex species. We also demonstrate simultaneous microwave three-wave mixing of two structurally related monoterpenes, menthone and carvone, in a chiral mixture, which is possible due to the high sensitivity of rotational spectroscopy to structural differences.
