Abstract

Techniques based on picosecond resonance-enhanced multiphoton ionization and mass-selective ion photo-dissociation are described as a means for studying complex reaction mechanisms in molecular clusters. A set of experiments is described that can identify the cluster-size specific reactions that occur by the overlapping processes of neutral dissociation/fragment ionization, parent ionization/dissociation, and parent ion photoexcitation/dissociation. These molecular beam techniques are demonstrated for the case of neutral and ionic photon transfer and evaporation in clusters of phenol in (NH3)n, as well for radical chemistry and van der Waals dissociation in (CH3I)n clusters.
