This paper presents an extension to our knowledge of Delta v = 1 and Delta v = 2 bands of carbon monoxide in the ground state, measured by Fourier transform infrared spectroscopy of glow discharge of formamidenitrogen mixture. Lines in declared bands are measured up to v = 30 for Delta v = 1 and up to v = 24 for Delta v = 2 band, by use of both InSb and MCT detectors, which have not been measured in the laboratory before. Dunham parameters obtained by fitting our lines are presented as well as comparison to other authors. The paper also demonstrates the interesting impossibility of sufficient population of Delta v = 2 band of CO when only pure CO is used in the glow discharge, instead of formamide-based mixture. Additionally, we present a non-LTE model to describe the intensity pattern of the Delta v = 1 and the Delta v = 2 bands of (CO)-C-12-O-16 experimental spectra by simulating the corresponding non-LTE vibrational populations of CO.
