Abstract
Besides the usual single-monomer evaporation, the (C3H8)n(C3H7+) clust er ions produced by electron-impact ionization of neutral propane clus ters have been observed to decay by an additional channel leading to e vaporation of up to four C3H8 monomers. It is shown that this addition al fragmentation channel is initiated by a new decay mechanism, i.e., the isomerization of an n-propyl ion to a more stable sec-propyl ion w ithin the cluster.
