Abstract:
Fermi resonance interaction has great influence on the near degenerated vibronic levels with same symmetry and its spectra of the polyatomic molecules, based on the perturbation theory, the influence of the Fermi resonance on the three vibronic levels under the fifth-order approximation is presented with the vibronic levels (04^00), (12^00) and (20^00) of CO2 as an example, the calculated results are in good agreement with the experimental ones. The Fermi resonance interaction on the vibrational spectra is also discussed.[著者文摘]
Key words:
Fermi resonance, intensity of the spectrum, vibronic energy level, fifth-order approximation
