利用IEO方法求解多原子分子的振动能谱

Deriving the vibrational energy spectrum of multi-atom molecular by virtue of IEO method

对于线性多原子分子体系模型,借助从海森伯方程出发的不变本征算符(IEO)方法,很方便地求解了相应哈密顿量的本征能谱与振动频率,从而给出IEO方法在分子物理中的进一步应用.

For some linear polyatomic molecules, one can conveniently derive energy spectrums and vibration frequencies of the corresponding Hamiltonians in terms of the invariant eigen-operator method stemming from Heisenberg equation. In this way, the further application of IEO method in molecular physics is introduced.
