摘要: 在真空条件下完成了X2 (X=Cl、Br)与AgOCN间的气-固异相反应,利用紫外光电子能谱(PES)仪,探测与确定反应产物是XNCO (X=Cl、Br),并推断其可能为一过渡态反应,生成中间络合物,新键产生与旧键断裂同时进行.

关键词: 气-固异相反应, 光电子能谱, AgOCN

Abstract: The gas-solid heterogeneous reaction between X2 (X=Cl, Br) and AgOCN has been investigated under the condition of super vacuum, HeI photoelectron spectroscopy (PES) indicates that XNCO was produced, and we deduce that an inter mediate complex in this process was formed, i.e. the generation of new-bond and the broken of old-bond were going simultaneously.
