Experimental and theoretical line parameters for self-and H2-broadened transitions in the first overtone band of CO

Abstract

International audienceIn this study we have re-analyzed high-resolution spectra of pure CO and CO broadened by hydrogen recorded in the spectral range of the first overtone band [1]. Self-and H2-Lorentzian pressure-broadened half-width, pressure-induced shift parameters, line mixing coefficients as well as line centers and intensities were obtained for 48 (P(24) to R(23)) ro-vibrational transitions belonging to the first overtone (2←0) band of 12 C16O at the ambient temperature (~298 K)
