Paper Abstract

The subject of this paper is the measured air-shifting coefficients for R70-R110 emission lines of the 12C16O2 in 4.3 micrometer band at temperatures of about 2000 K. The spectra were recorded on a Littrov type grating monochromator with a resolution of about 0.05 cm-1. A nonlinear least-squares fitting technique was used. The absolute error in lineshifts was estimated to be about 0.002 cm-1. The significant shifts (reaching 50 times the absolute uncertainty of experimental frequencies), strongly depending on the rotational quantum number were measured. The obtained results were compared with our previous measurements pressure-shift of R54-R72 lines at room temperature.
