Multiple features associated with transitions of the near T-shaped and linear Ne⋯I 35,37Cl(X,ν′ = 0) conformers are observed in laser-induced fluorescence spectra recorded in the ICl B-X, 2-0 and 3-0 spectral regions. The T-shaped complexes access the lowest intermolecular vibrational level, n′ b = 0, within the Ne + ICl(B,ν′) potential, while the linear complexes access four intermolecular bending levels, n′ b = 1-4, that form a progression of features up to the Ne + ICl(B,ν′) dissociation limit. The binding energy of the energetically more stable, ground state linear Ne⋯I 35Cl(X,ν″ = 0) conformer is measured to be 84(1) cm -1 in action spectroscopy experiments.
