摘要: 采用光外差-速度调制分子离子吸收光谱技术,在近红外波段11 387~11 800 cm-1范围内,首次对O2+第二负带(A2Πu -X2Πg)(5,21)带进行测量和分析.采用有效Hamilton量,在非线性最小二乘意义上拟合获得了该振动带下态精确的分子常数.Abstract: The (5, 21) band in the A2Πu -X2Πg system of O2+ was studied for the first time, by employing optical heterodyne detected velocity modulation spectroscopy in the region of 11 387~11 800 cm-1. Adopting effective Hamiltonians, the precise molecular constants of the lower level involved were obtained by a nonlinear least-squares fitting procedure.
