Sequential two photon studies of Xe:Cl2 complexes in liquid Ar are reported. The first photon
prepares the excited state complex Xe:Cl2

u . A second photon accesses either the molecular ion
pair state, Xe:Cl Cl , or the contact charge transfer transition, Xe Cl2 . The latter dissociates to
Xe Cl Cl even though the product is formed at threshold. The former undergoes charge
rearrangement and decays radiatively via Xe Cl2
