氮分子第一正带系振子强度的理论计算
Theoretic calculation of the oscillator strength of the first positive bandsy stem of the nitrogen molecule
摘要
将前文提出的选择组态函数的准则从双电子激发扩充到三电子激发;采用投影算符消除其它多重态的影响;根据组态互作用法计算了氮分子第一正带系的振子强度,其值为0.00198,与实验完全吻合。
Abstract
The set of criteria for selecting configuration function, presented in the previous paper[2], are extended from double-electron excitation to three-electron exoetation. The effect of other multiplicate states on the excited B 3Πg and A 3Σu++ states are excluded by using the projection operator. By means of CI method the oscillator strongth of the first positiue band system of N2 is calculated. The calculated value is 0.00198, being in good agreement with experimental values.
