摘　　要：我们提出一种描述XH3分子的伸缩和弯曲振动的U(2)代数哈米顿量,其中包括了伸缩和弯曲振动的费米共振耦合,用它来拟合CH3Cl分子的实验数据,结果表明有较少参数的代数模型算得的偏差比其它模型算得的偏差要小.An algebraic Hamiltonian describing both stretching and bending vibrational energy levels of molecule XH3 is presented, where Fermi resonance couplings between the stretch and bend modes are included. The Hamiltonian is employed to fit the observed vibrational spectra of CH3C1. The result shows that the algebraic Hamiltonian with few parameters reproduces the observed experimental values with smaller standard deviation than other model.
