摘要：

The species ArCO2 produced by adiabatic expansion is structurally characterized by molecular beam electric resonance spectroscopy. ArCO2 is shown to have C2v symmetry. The spectroscopic constants obtained are: A0 11914(80) MHz B0 1979.87(25) MHz C0 1682.75(70) MHz τaaaa -15.97 kHz τbbbb -98.3(20) kHz τaabb 0.0 τabab -907.(120) kHz The derived structural constants for ArCO2 are: R0 3.493(10) Å ks 0.0174(5) Mdyne/Å ωs 37.5(7) cm-1 kb 0.0083(10) Mdyne/Å ωb 27.5(20) cm-1 μ 0.06793(20) D Comparison is made with a number of proposed Ar-CO2 intermolecular potentials. The determined force constants are shown to be poorly fitted by a spherical argon-oxygen interaction. © 1979 American Institute of Physics.
