摘要：
Consecutive bimolecular ion-molecule addition and elimination reactions have been observed within van der Waals clusters of isoprene following electron impact ionization at pressures of 10(-8) Torr. A magic number has been observed for C14H21+ ion and attributed to a stable cyclic structure. The results suggest that cationic polymerization of isoprene proceeds via the formation of the stable dimer C10H16+ which, most likely, has a structure similar to limonene and can undergo further addition reactions to generate larger ions.
