利用李群方法与二次量子化理论计算了平面XY_3型分子的转一振能级。结果表明,如果将分子的转动与振动均看作是谐振子,则可导出这种分子的转一振能级公式。
The rotational vibrational energy levels of planar XY_3 molecules were calculated by using the Lie group method and the second quantum theory. The results show that if both the molecular rotation and vibration are considered as harmonic oscillator, then we can derive the formula of this molecule’s rotational vibration level.
