由空间实验室3号（1985年4月30日至6月5日）上的大气痕量分子光谱仪（ATMOS）以0.01 cm−1的分辨率记录的平流层的太阳红外吸收光谱显示，在1925至1960 cm−1和1249至1255 cm− 1区域存在许多以前未观测到的吸收特征，其中一个在774 cm−1。在与实验室光谱比较的基础上，这些特征已被确定为分别属于碳酰氟的ν1，ν4和ν6带。根据对ν1和ν6波段的分析，推导出17 ~ 40 km之间COF 2的体积混合比。
Infrared solar absorption spectra of the stratosphere recorded at a resolution of 0.01 cm−1 by the ATMOS (Atmospheric Trace Molecule Spectroscopy) instrument from onboard Spacelab 3 (04/30 to 05/6/85) have revealed the existence of many previously unobserved absorption features in the 1925 to 1960 cm−1 and 1249 to 1255 cm−1regions and one at 774 cm−1. On the basis of comparisons with laboratory spectra, these features have been identified as belonging to the ν1, ν4; and ν6 bands of carbonyl fluoride, respectively. Volume mixing ratios of COF2 between 17 and 40 km have been deduced from analysis of the ν1 and ν6 bands.
