Studies on the full vibrational energies and dissociation energies for some states of alkali hydride molecules
【摘要】 应用作者建立的基于微扰理论能级表达式的代数方法,研究了碱金属氢化物双原子分子6LiH,7LiH,NaH,KH,RbH和CsH的A1Σ+电子态的完全振动能谱{Eυ},并应用基于代数方法的代数能量方法分别研究了以上各分子电子态的离解能.得到了这些电子态的精确的振动光谱常数和包括接近分子离解极限在内的完全振动能谱以及正确的理论离解能,从而为许多需要这些双原子分子的精确振动光谱的科学研究提供了必要的数据.
【Abstract】 The full vibrational energy spectra for the A~1Σ~+ states of alkali hydride diatomic molecules ~6LiH, ~7LiH, NaH, KH, RbH and CsH have been studied using algebraic method (AM), and the dissociation energies D_e of these molecules have also been studied using algebraic energy method (AEM). The results show that the AM produces accurate full vibrational energy spectra for these molecules for the first time so far as we know, and based on these AM spectra, the AEM can give correct molecular dissociation energies D_e for these systems.
