The absorption spectra of carbon monoxide have been recorded in the 6000–6450 cm⁻¹ wavenumber regions using the Bruker IFS 125 HR Fourier transform spectrometer and a 30 m multipass cell with the White-type optical system. The spectra were recorded at spectral resolution of 0.008–0.012 cm⁻¹, path length up to 1058 m, and at pressure range from 30 to 320 mbar. The temperature was about 301 K. The lines of the 3-0 bands of six isotopologues ¹²C¹⁶O, ¹³C¹⁶O, ¹²C¹⁸O, ¹²C¹⁷O, ¹³C¹⁸O, ¹³C¹⁷O and the lines of the hot 4-1 band of ¹²C¹⁶O were assigned in the spectra. The line intensities and the self-broadening coefficients were measured. In the case of the principal isotopologue the line intensities were determined for the lines with the angular momentum quantum number J up to 41. The effective dipole moment parameters describing the line intensities of the observed bands were fitted to the observed values of the line intensities. The uncertainty of the line intensity measurements for the strong unsaturated and unblended lines of the principal isotopologue varies between 2% and 2.5%. The comparison of our measured line intensities to those of other authors and of the HITRAN2016 database is given.
