Absorption spectra of HCFC-22 around 829/cm at atmospheric conditions

Spectral absorption coefficients of HCFC-22 have been measured around 829/cm in the laboratory at various temperature-pressure combinations chosen to represent tangent heights (as in solar-occultation experiments) or layers in the atmosphere. The data measured employing the Doppler-limited spectra resolution (about 10 exp -4/cm) of a tunable diode laser spectrometer are free of instrumental distortion and are more practical in this case than the spectral line parameters adapted in conventional line-by-line procedures for analyzing atmospheric spectra. The present data obtained with N2 as the broadening gas are shown to be directly applicable to the real atmosphere.
