dc.description.abstractMeasurements of the collision-induced absorption of $O_{2}$ in the vicinity of the electric-dipole-forbidden vibrational fundamental have been made in pure $O_{2}, O_{2}/N_{2}$ and $Ar/O_{2}$ mixtures. The goal is to provide reliable absorption coefficients to allow accurate retrievals of stratospheric concentration profiles of $H_{2}O$ vapor, $NO_{2}$, and sulfate aerosols from limb-viewing filter radiometers, such as those mounted on the UARS and future EOS platforms. Here, spectra were recorded at a resolution of $0.5 cm^{-1}$ using a Fourier-transform infrared spectrometer. Measurements were made using an optical pathlength of 84 m, sample densities up to approximately 8 amagats, and sample temperatures between 225 K and 300 K. The present results are in good agreement with the earlier less precise measurements of Orlando et al. on $O_{2}$ and $O_{2}/N_{2}$ mixtures and Thibault et al. on pure $O_{2}$. Studies of $Ar/O_{2}$ mixtures indicate that the observed structure on the high-frequency shoulder of the band, previously attributed to dimer bound states by Henderson and Ewing, is more likely due to line mixing of pure quadrupole transitions of $O_{2}$, as originally suggested by Vigasin.en_US
