In the 4.8 μm spectral region, intensities of lines belonging to the 3 following perpendicular bands of 12C16O2 have been measured: the ∏←∑ cold band 11101-00001 centered at 2076.856 cm-1, the Δ←∏ hot band 12201-01101 centered at 2093.345 cm-1, and the ∑←∏ hot band 20001-01101 centered at 2129.756 cm-1. Fourier transform spectra, under a resolution limit of about 0.0023 cm-1, have been used. For each band, the square of the vibrational dipole-moment matrix element and the Herman-Wallis coefficients have been determined. These results are compared with the previous experimental results included in the last edition of the HITRAN molecular database, as well as with new results obtained by the Direct Numerical Diagonalization method.
