The Influence of Isotopic Substitution on the Effective Dipole Moment Parameters of CO2 Molecule

The influence of isotopic substitution on the values of the effective dipole moment parameters of the q(0)J, qJ, q(2)J, and q(3)J types has been studied for carbon dioxide bands, which are active only in the case of asymmetric isotopologues of this molecule. It has been shown that the effective dipole moment parameters for these bands strongly depend on the mass difference of the oxygen atoms entering into the molecule composition.
