Abstract:

The dipole moment effect, which occurs due to isotopic substitution of one oxygen atom in the absorbing molecule, on the collisional half-widths of rotation-vibrational lines in the ν3 band in the case of perturbation by the main isotopic species 16O12C16O is investigated. Self-broadening coefficients of the carbon dioxide isotopic species lines were calculated by two methods: semi-empirical and semiclassical. The difference of line broadening for different isotopic species is obtained using both methods.

Keywords:

contour of spectral line, self-broadening coefficient of spectral line
