Abstract
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.
