研究領域:
  • 研究碳氫化合物分子之反應動態學,可幫助瞭解星體的演化、燃燒機制、環境污染與能源開發等議題。結合交叉分子束系統以及同步輻射真空紫外光游離法,為研究化學反應動態學的一項重要利器,可測量電子式游離法無法觀測的產物。已對碳原子與乙烯、丙烯、氟化乙烯、氯化乙烯的反應動態學做深入的研究與探討;瞭解碳-氫交換、碳-氟交換、碳-氯交換、碳-甲基交換之機制。未來的研究主題將著重在碳氫自由基(如:CH、C2H、C3H、C4H、C5H、C6H)與不飽和碳氫化合物(如:C2H2、C3H4、C2H4、C3H6、C4H2、C6H2)之化學反應動態學研究。此一系列研究可幫助瞭解宇宙中聚炔烴(polyyne)及其衍生物的形成機制。藉由測量產物之飛行時譜、動能分布、角度分布、路徑分支比、及游離光譜來探討其反應動態學。此外,使用ab initio方法計算化學反應位能面,以及使用RRKM方法計算反應速率常數與反應路徑分支比。結合交叉分子束實驗及量子理論計算,將可以對此一系列化學反應作深入的探討。
