摘要
The absorption spectrum of N2＋ has been studied using optical-heterodyne velocity mod- ulation spectroscopy in the near-infrared region. The observed spectral lines were assigned to the （3,1）, （4,2）, （5,3）, （8,5） bands of the A2Ⅱu-X2∑g＋ system and the line lists were pro- vided. The （5,3） band was studied for the first time. Fourteen rotational-resolved bands in literatures were fitted together with our observed bands and the molecular constants were obtained for VA=0-9 and vx=0-5.
