✦ Synopsis
Line-mixing effects have been studied in two Q branches of the absorption spectra of CO 2 , in mixtures with nitrogen, oxygen, and argon. The corresponding transitions are (20 0 0) I R 01 1 0 and (12 2 0) I R 01 1 0, centered near 2130 cm 01 and 2093 cm 01 , respectively. Line-mixing effects have also been examined in two Q-branches of pure N 2 O, corresponding to the 13 1 0 R 00 0 0 and 13 1 0 R 01 1 0 transitions, centered near 3046 cm 01 and 2457 cm 01 , respectively. Good agreement is obtained between the experimental results and computations taking line mixing effects into account with a phenomenological model for the relaxation matrix.
