Abstract

The dissociation dynamics of He₂⋯I³⁵Cl complexes prepared with varying amounts of intermolecular vibrational excitation within the 2He + I³⁵Cl(B,v′ = 3) potential energy surface are reported. For the intermolecular level associated with one He atom in an energetically excited, delocalized state and the other localized in the lowest-energy, T-shaped potential minimum, the higher-energy He atom dissociates preferentially. The binding energy of the ground-state He₂⋯ I³⁵Cl(X,v″ = 0) conformer with a police nightstick geometry (one He atom in the T-shaped minimum and the second in the linear well) is measured to be 38.6(9) cm^-1.
