摘要  通过用莫尔斯提出的双原子分子势函数,求解双原子分子振动的薛定谔方程,讨论了双原子分子振动光谱.结果表明,莫尔斯势包含双原子分子振动的一级非谐性质,它能够较好地反映双原子分子振动情况.得出了离解能与振动光谱常数之间的关系. Through using potential function of diatomic molecules put forward by P.M.Morse and solving Shrdinger vibrating equation of diatomic molecules,discuss vibrating spectrum of diatomic molecules.The result shows that P.M.Morse's potential function includes the first non-harmonic term of vibration of diatomic molecule and well reflects the situation of vibration of diatomic molecules.It concludes the relationship of energy of dissociation and vibrating spectral constant.
