摘　　要：采用双原子分子及离子体系的完全振动能谱和精确振动光谱常数的代数方法(Algebraic Method),根据实验所得的一组精确的12C16O分子X1Σ+基态低振动能级计算出其精确振动光谱常数和完全振动能谱;并结合Herzberg的同位素效应理论得出实验上缺乏的12C18O和13C16O分子X1Σ+基态的各项光谱常数,计算出它们之间的同位素位移。With the algebraic method of studying the full vibrational energy and precise vibrational spectrum constants in diatomic molecules and ions systems,a series of precise vibrational spectrum constants and full vibrational energy spectrum were generated based on a number of experimentally-measured lower vibrational energy levels of 12C16O.The ground states spectrum constants of 12C18O and13C16O and the isotope shift of them have also been obtained by combining algebraic method with the Herzberg＇s isotope effect theory,which may be important and useful for the experiment measurements.
