Abstract:
The dynamics of the Cl+SiH4 reaction has been studied using the universal crossed molecular beam method. Angular resolved time-of-flight spectra have been measured for the channel SiH3Cl+H. Product angular distributions as well as energy distributions in the center-of- mass frame were determined for the channel. Experimental results show that the SiH3Cl product is mainly backward scattered relative to the Cl atom beam direction, suggesting that the channel takes place via a typical SN2 type reaction mechanism.

摘要:
利用通用型交叉分子束研究了氯原子与硅烷的反应,观测到SiH3Cl+H通道. 测量到产物SiH3Cl在实验坐标下的角度分辨的飞行时间谱,获得了这个通道质心坐标下的产物角分布和动能分布. 结果表明,相对于氯原子束方向,产物SiH3Cl主要是后向散射,说明这个通道主要是通过典型的双分子亲核取代反应(SN2)机理进行的.
