摘要
K2分子的各电子态的能谱研究以及分子离解能的研究很活跃,也具有很重要的意义,然而对K2分子的多数电子态,用实验的方法一般只能获得低振动能级的能谱,对于高阶振动能谱,实验是很难获得的,从而用实验的方法来获得各电子态的完全振动能谱是很困难的。利用文献中实验测得的低阶振动能谱,运用SUN、REN等人提出的代数方法(AM)获得了K2分子A1∑u+电子态的高能级振动能谱,从而得到电子态的完全振动能谱,进而得到比较精确的离解能的理论值。
The vibrational spectrum and molecular dissociation energies of the K2 electronic states are important in studies and applications. Modem experimental methods or accurate quantum theoretical methods usually may obtain a vibrational energy spectra, but may be difficult to have all high vibrational energies for K2 electronic states. The authors get accurate vibrational spectroscopic constants and full vibrational energy spectrum from the exper/mental spectrum, and the dissociation energies of the A1∑u^＋ electronic states of K2 using the SUN and REN＇s algebraic method （AM）.
