Multi-dimensional stereodynamics in the radical combustion reaction

我们开发了OH（^2Π）、CH（^2Π）、CO（^3Π）自由基的高强度定向自由基束，并成功地研究了分子-分子体系的多维立体动力学。特别是，我们可以验证一种新的反应性，即“旋转相关反应性”，即CH+O_2燃烧反应的特定反应性取决于两个分子反应物之间的旋转态组合。此外，我们还开发了一种新的实验技术，利用电六极制备的定向光束和磁六极制备的定向分子相结合的方法来研究多维立体动力学。该技术已成功应用于准分子生成反应。

We have developed a high intense oriented radical beam for OH(^2Π), CH(^2Π), CO(^3Π) radicals and succeeded to study the multi-dimensional stereodynamics on the molecular-molecular systems. Especially, we can verify a novel reactivity, "rotationally correlated reactivity", that means a specific reactivity depending on the combination of the rotation states between two molecular reactants for the combustion reaction of CH+O_2. In addition, we have developed a novel experimental technique for studying the multi-dimensional stereodynamics by means of the combination of the oriented beam prepared by an electric hexapole and the oriented molecule prepared by a magnetic hexapole. This technique has been successfully applied to the reaction of excimer formation.
