Infrared spectroscopic detection of sulfur hexafluoride (sf6

Absorption by sulfur hexafluoride (SF 6) has been detected in high‐resolution infrared solar spectra of the lower stratosphere and upper troposphere. The identification is based on measurements of the intense, unresolved ν3 band Q branch at 947.9 cm −1 in solar occultation spectra recorded near 31°N and 47°S latitude by the Atmospheric Trace Molecule Spectroscopy (ATMOS) Fourier transform spectrometer on April 30 to May 1, 1985, during the Spacelab 3 shuttle mission.Get price
