| Popis: | A quantitative treatment of adiabatic and non-adiabatic effects in the vibration-rotational spectra of a linear polyatomic molecule is applied to the available spectral data of carbon dioxide. The results include a potential-energy function in displacement coordinates up to the sixth power and parameters corresponding to adiabatic and non-adiabatic effects for the primary vibrational and rotational quantities that are independent of nuclear masses, the equilibrium internuclear distance R BO e = (1·159 979 2 ± 0·000 002 2) × 10-10 m, and an estimate of the rotational g factor that agrees with the value more accurately determined from experiments on molecular beams. |
