Nitrogen-Broadening Parameters for Atmospheric Spectra Modelling of the ν3 Band of SF6

Nitrogen-Broadening Parameters for Atmospheric Spectra Modelling of the ν3 Band of SF6

The infrared absorption of the ν3 band region of SF6, at temperatures spanning the 130 to 297 K range, has been reexamined using improved instrumentation with one goal: to estimate the broadening of parameters by nitrogen gas. These parameters are compared to previous literature predictions and an e...

Zusammenfassung:The infrared absorption of the ν3 band region of SF6, at temperatures spanning the 130 to 297 K range, has been reexamined using improved instrumentation with one goal: to estimate the broadening of parameters by nitrogen gas. These parameters are compared to previous literature predictions and an extended set of IR cross-sections is proposed and compared to other existing datasets.
