Recombination of Br2- photodissociated within mass selected ionic clusters

Article abstract of DOI:10.1063/1.454458

Photofragmentation studies of mass selected Br2^-*(CO2)n, n<24, cluster ions are presented.The heterogeneous cluster ions are synthesized in a supersonic expansion crossed with an electron beam.Thesc ionic clusters are mass analyzed in a time-of-flight mass spectrometer prior to photodissociation of the Br2^- absorber in the cluster.Mass analysis of the ionic photofragments shows that in some cases the photodissociated Br2^- has recombined and in other cases a Br atom has escaped from the cluster.The branching ratio for recombination depends on both the size of the initial cluster ion and the photodissociation wavelength.The photofragmentation data are consistent with a recombination mechanism dominated by attractive forces in the smaller clusters and repulsive interactions in the larger clusters.
