| 摘 要： | 研究了CCl4的ν1+ν4与ν3的费米共振现象。结果表明ν1振动频率是影响费米共振红外和拉曼光谱特性参数(峰位差Δ,耦合系数W,光谱强度比R,非谐力常数K等)的主要因素,而其光谱强度大小却与这些参数无直接关系。本文用Berttran理论和群论对这一结果给以解释。该研究对理解费米共振现象和分子结构研究中的谱线归属等有参考价值。

| Abstract: | The ν1+ν2 and ν3 bands of CCl4 at Fermi resonance are studied.It is shown that the frequency ν1 is the major factor that impacts the characteristic parameters of infrared and Raman spectra at Fermi resonance and the intensity has no direct relation with these parameters.The results are interpreted from group theory and the Bertran's theory.This report provides reference value for the understanding of Fermi resonance and the band assignment in the study of molecular structures. |
