| 摘 要： | 本文考虑了分子振动非谐性所引起的振动能级之间的费米共振相互作用,利用定态微扰论,从理论上系统地分析了两态和三态之间的费米共振相互作用对能级能量、态函数和谱线强度的影响,在三阶非谐性近似下,得到了计及费米共振相互作用在内的能级能量、态函数和谱线强度的数学解析表达式.

| Abstract: | The Fermi resonance interaction between the vibronic levels caused by the molecular inharmonic vibration is discussed.Based on the perturbation theory,the influences of the Fermi resonance interaction between the two and three vibronic levels on the level energy,wavefunction,and the spectral line intensity are investigated in detail respectively.The analytical expressions of the vibronic level energy,wavefunction,and spectral line intensity with the consideration of the Fermi resonance interaction are also obtained under the third order inharmonic approximation. |

| Keywords: | fermi resonance vibronic level wavefunction spectral line intensity |
