Abstract

The goal of this paper was to re-evaluate 3D potential energy surface of the Ar–N₂O complex containing N₂O monomer v₃ stretching vibrations. Two vibrational potentials for v₃ = 0, 1 were obtained and then used to predict infrared spectra and spectroscopic constants of the Ar–N₂O complex, which showed excellent agreement with the experimentally obtained infrared spectra.
