摘 要:
鉴于I2分子电子态的振动能谱和分子离解能De在实际研究和应用中的重要性,本文应用SUN,REN等人提出的基于微扰理论的代数方法(AM),研究了I2分子A’(2u^3Ⅱ),A^3Ⅱ(1u),1g(^1D),0^+g(^1D)和F’(0^+u)电子态的振动光谱常数和完全振动能谱{Ev};使用基于AM的代数能量方法(AEM)获得了这些电子态的高激发振动态的完全振动能谱和分子离解能,为许多需要这些难以从实验中获得双原子分子的精确振动光谱和离解能的科学研究提供了必要的物理数据。[著者文摘]

Abstract:
In view of the importance of the full vibrational spectrum and the molecular dissociation energies of I2 molecule to many studies and applications, this paper uses the SUN^+ and REN's algebraic method (AM) which is based on perturbation theory and algebraic method (AM) and algebraic energy method (AEM) which is based on the AM to study the vibrational spectroscopic constants and full vibrational spectra{ Ev } including the excited high - lying vibrational energies of electronic states A'(2u^3Ⅱ),A^3Ⅱ(1u),1g(^1D),0^+g(^1D) and F' (0^+u) of I2 molecule, and obtain the accurate molecular dissociation energies(Do) of these states. The full vibrational spectra, especially the high-lying vibrational energies and dissociation energies are difficult to gain from experiment, so this study can offer physic data for scientific research.[著者文摘]
