Résumé	The infrared spectrum of the weakly bound C₂H₄-CO₂ complex is investigated in the region of the ν₃ fundamental band of CO₂ (≈2350 cm⁻¹), using a tunable OPO laser source to probe a pulsed supersonic slit jet expansion. The spacing of the various K-subbands in this perpendicular (ΔK = ±1) spectrum is very irregular, and the pattern of irregularity is quite different from that observed previously in another C₂H₄-CO₂ band by Bemish et al. [ J. Chem. Phys. 1995, 103, 7788 ]. But by allowing for the different symmetry of the ν₃ (CO₂) upper vibrational state, both results can be strikingly well explained using the "double internal rotor" model as described by Bemish et al.
