Chemistry Within van der Waals Cluster of Unsaturated Molecules: Observation of Cationic Polymerization

We present in this paper the observation of intracluster ion-molecule polymerization reactions within clusters containing molecules which possess double or triple carbon-carbon bonds. This effect is borne out by the observation of unusual magic numbers in the cluster ion distribution only under expa...

Description
Summary:We present in this paper the observation of intracluster ion-molecule polymerization reactions within clusters containing molecules which possess double or triple carbon-carbon bonds. This effect is borne out by the observation of unusual magic numbers in the cluster ion distribution only under expansion conditions which favor the production of large neutral clusters. These magic numbers are rationalized in terms of the production of covalently bonded cyclic molecular ions which terminate the cationic polymerization process.
