Polymerization of Ionized Acetylene Clusters into Covalent Bonded Ions:Evidence for the Formation of Benzene Radical Cation

摘要

The chemistry of acetylene has received considerable attention and continues to be an active area of research.This is due not only to the acetylene polymerization to produce a variety of industrially and technologically important conducting polymers but also to the important roles of acetylene in flames and combustion processes,particularly for the mechanism of soot formation,and in interstellar clouds particularly for the origin of larger hydrocarbon and other complicated molecular species observed in interstellar medium.
