摘要
用代数能量方法得到了Li2分子9个电子态的振动光谱常数,完全振动能谱{Ev}和分子离解能De.结果显示:振动能谱{Ev}不仅能重复有限的已知实验数据,而且能给出一些未知的高阶振动能量.用AEM所得到的离解能很好的符合了已知的实验值De.对一些双原子系统,当无法得到实验离解能时,用AEM方法也能得到合理的近似离解能值.
The vibrational spectroscopic constants, full vibrational energy spectra{ Ev } , and molecular dissociation energies De, for nine electronic states of Li2 molecule are obtained using algebraic energy method （AEM）. The results show that the generated vibrational energy spectrum { Ev} not only reproduces limited known experimental data but also correctly gives all unknown high-lying vibrational energies. The AEM dissociation energy excellently agrees with known experimental De, and the AEM can generate reasonable approximate De for the diatomic system whose experimental dissociation energy is not available.
