用代数方法(AM)可以获得双原子分子包含最高振动能级在内的所有高阶振动能级的完全振动能谱;基于Leroy和Bernstein的能级表达式,研究了卤族元素双原子分子Cl2-A’^3П(2u)、Br2-X^1∑g^+和I2-Ou^+电子态的完全振动能谱和离解能,得到的理论结果与实验符合得很好.
The algebraic method (AM) and a new formula for dissociation energy were used to study full vibrational energies {Eu^AM } and dissociation energies De^AM of three electronic states Cl2-A'^3П(2u)、Br2-X^1∑g^+ and I2-Ou^+ of diatomic halogen molecules. The obtained results are in agreement with known experimental data.
