Abstract

The formation of negative ions in monosubstituted halobenzenes by electron transfer collisions was studied using crossed molecular beam technique. Time-of-flight mass spectrometry was used to detect negative ions and a quasidiatomic dynamical behavior in the fragmentation was found. A minor negative fragmentation was also reported for the phenyl ring. The major abundance of the halogen negative ions was supported by density functional theoretical calculations and it explained the completely different behavior in the negative fragmentation of these aromatic systems.
