Air pressure broadening and shifting of high-J lines of (00011) <-- (00001) band of super(12)C super(16)O sub(2)

The absorption spectra of carbon dioxide (isotope 626, natural abundance in air, ambient temperature) have been studied at total pressures 68-570 Torr with spectral resolution 0.003-0.005 cm super(-1). The spectra were measured in the spectral domain of 2273-2393 cm super(-1) by FTIR spectrometer Bruker IFS 125 HR equipped with White-type multipass cell (6.4-41.6 m) and with a cell having 10 cm optical path length. Pressure broadening and shift coefficients were obtained from a series of spectra by means of a nonlinear least-squares spectral fitting technique for the lines of the (00011)
