摘要: 根据塞曼效应理论和激光磁共振光谱技术(LMR)的基本原理,讨论了双原子分子2∏态的塞曼效应特性并导出了解释分子塞曼跃迁的简明代数拟合方程,用这些方程对14N16O(X21/2.3/2)及15N16O(X23/2)(v=1←0)的LMR谱线进行数据拟合,得到塞曼跃迁上、下子能级的gJ因子值和二级塞曼效应因子k2.将按Hund耦合情形(a)及过渡情形(ab)的理论和拟合方程计算出的磁场位置分别与实验结果相比较,结果表明对NO分子而言,过渡情形(ab)能较真实反映它的耦合情况,且在较高强度磁场下,必须计及二级塞曼修正验证了采用上述代数拟合方程实现新分子LMR谱线标识和指认的可靠性,并提供了系统的处理方法.

Abstract: According to the Zeeman effect theories and the principle of the technique of laser magnetic resonance spectroscopy, the characteristics of Zeeman transitions for 2∏ electronic stateof diatomic molecules were discussed and brief algebraic fitting equation for Zeeman transitions was developed. Fitting the observed LMR spectra of NO(X2∏)v=1←0 to theses equation, g factors and the second order Zeeman factor k2 were determined. A comparison of theresults calculated by Hund's case (a) and the Hund's intermediate case(ab) with the obserying spectra suggests the superiority of the intermediate case(ab) to case(a) and the necessityto consider the second order Zeeman effect in strong field even for NO with Av/Bv≈80. Itprovides a systematic technique for diatomic and linear Polyatomic molecules with non-zeroorbital angular momentum, and confirms the reliability of the quadratic Zeeman effect theoryfor this kind of molecules.
