Abstract	The infrared spectrum of CO₂-Ne complex is studied in the region of the CO₂ ν₃ fundamental vibration. The vibrational fundamentals for both CO₂-²⁰Ne and CO₂-²²Ne are analyzed in combination with available microwave data. In addition, combination bands involving the intermolecular bending mode are observed, leading to the determination of the bending frequency. For the hot band CO₂ transition, (01¹1) ← (01¹0), detection of the weak CO₂-Ne spectrum reveals the symmetry breaking of the CO₂ ν₂ bending mode induced by the Ne atom, with the out-of-plane component determined to lie 0.057 cm−1 higher in energy than the in-plane component.
