摘要
利用激光溅射的方法,在射频离子阱中产生并囚禁了C+n(n=3,4,5),进而利用离子阱的质量选择存储和离子存储时间长等特点,在其中开展了C+n同O2的化学反应研究。得到了反应物的速率常数和反应产物分支比。根据热化学计算,分析了反应进行的主要通道。
C + n(n=3,4,5) cluster ions have been produced and stored in our RF ion trap by method of laser ablation Furthermore,by means of the advantage of mass selective storage and long storage time of ion trap,we have developed the study of chemical reactions of C + n cluster ions with O 2 in the ion trap Chemical reaction rate constants of reactants and branching ration of products have been discussed through the results from the endothermicity and exdothermicity of these reaction processes
