✦ Synopsis
The effective operator approach is applied to the calculation of the spectra of 16 O 12 C 17 O and 16 O 12 C 18 O in the mid infrared. Using the eigenfunctions of the effective Hamiltonians previously derived for each of these species, parameters of the corresponding effective dipole moment operators have been fitted to more than 400 observed line intensities of cold and hot bands covering the m 3 and 2m 1 spectral regions. New line intensities measurements of 16 O 12 C 18 O have been performed. The new observed line intensities have been also included into the corresponding fit. The fittings have been achieved within the experimental errors. A comparison of calculated line parameters with those provided by the HITRAN and GEISA databases is given.

The effective operator approach is applied to the calculation of the line positions of two isotopic species, 16 O 12 C 17 O and 16 O 12 C 18 O, of the carbon dioxide molecule. More than 6600 observed line positions of 72 bands of 16 O 12 C 18 O selected from the literature have been used to derive 7
Lorentz pressure-broadening and pressure-induced shift coefficients along with their temperature dependences have been determined for over forty P-and R-branch transitions in the fundamental band of 12 C 16 O broadened with helium. A total of nineteen spectra recorded at various temperatures (C24 to
