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11387~11800 cm^-1范围内,首次对O_2^+第二负带(A^2П_u-X^2П_g)(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.[著者文摘]

Abstract:
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.[著者文摘]
