The absorption spectrum of the weakly bound cluster CO₂-NO has been observed by probing the v₃ asymmetric stretch of CO₂. Clusters were formed by supersonic expansion of a mixture of NO:CO₂ in a ~7:1 ratio using He as the carrier gas. Etalon, reference and signal spectra were recorded simultaneously using a transient digitizer and a 386 PC. The spectrum was recorded between 2344.6 -2349.6 cm^-1. The structure of the dimer will be discussed.
