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(A2Пu-X2Пg)(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. The（5, 21） band in the A^2П_u-x^2-П_g system of O_2^＋ 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.
