| 摘 要： | 通过对NO与He流动混合气体放电, 产生了激发态的NO(a4Πii) 分子. 利用光外差-浓度调制吸收光谱技术测量了NO分子在12530-12850 cm-1波段内的吸收光谱, 并标识出b4Σ--a4Πi(4,0)带在该波段内的324条光谱跃迁谱线. 采用标准4Σ--4Πi哈密顿量模型, 通过非线性最小二乘法拟合其中267条谱线, 拟合残差(0.0071 cm-1) 接近实验系统测量误差(0.007 cm-1). 获得的主要分子常数与文献提供的常数符合, 并且拟合得到了精细结构分子常数.

| Abstract: | The absorption spectrum of NO is analyzed in a range of 12530-12850 cm-1 using optical heterodyne concentration modulation spectroscopy in an AC glow discharge of He/NO mixture. Among all the spectral lines, 324 lines are assigned to the (4, 0) band and 267 ones are fitted to the Hamiltonians of the b4Σ--a4Πi system by a non-linear least-square fitting procedure. A residual (0.0071 cm-1) comparable to system error (0.0071 cm-1) is obtained. The main molecular constants are consistent with those reported in the literature and the fine structure constants are fitted. |
