摘　　要：文章给出了A H健振动频率γA H与价电子数、有效电荷密度、键长的关系方程 :γA H=52 0 8φ1 +6 9.50 φ2 - 2 6 0 .2 (cm- 1 )。用该式计算了一些常见A H键的振动频率γA H,结果与实验数据相差很小。This paper presents a relation equation: γ A H =5 208 φ 1+69.50φ 2-260.2 (cm -1 ),which shows the relationship between the vibration frequency of A H bond and the valence electron number,effective electronic charge density and bond length of A H bond.By using this equation,the calculation of some common vibration frequencies of A H bond has been done with little difference between the result and test data.
