The weakly-bound complex Cl·N2O studied by high resolution photodetachment photoelectron spectroscopy

Abstract

Zero kinetic energy photoelectron spectroscopy of the weakly bound complex Cl⁻·N₂O is presented. Adiabatic detachment energies between the anionic complex and the neutral complex states X_1/2, I_3/2, and II_1/2 as well as frequencies of van der Waals modes are supplied. Supported by theoretical simulations, these results correlate with a T-shaped structure of the anionic and an L-shaped structure of the neutral molecular complex. The weakly bound neutral complex Cl·N₂O has been discussed as a prereactive state of the chemical reaction Cl + N₂O → ClO + N₂ [A. Lesar, M. Hodoscek, M. Senegacnik, J. Chem. Phys. 1996, 105, 917].
