Abstract:	The infrared spectrum of CO₂ in D₂ matrices has been found to be particularly sensitive to the addition of small amounts of N₂ impurity. For percentages of added N₂ (relative to D₂) of 0.06–2.5% a complex v₃ band was found which could be decomposed into the sum of five components. The effects of other impurity molecules were also examined. No effects in the spectrum were detected for O₂ Ar or H₂ impurity at the 0.5 or 1.0% level but CO at the 0.1–1.0% level had a marked effect on the v₃ region which differed from that of N₂. The effects of added N₂ or CO on the v₂ region were less marked.
