Abstract:
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 A2Πu-X2Σ+g system and the line lists were provided. 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 υA=0-9 and υX=0-5.

摘要:
利用光外差速度调制分子光谱技术测得氮分子离子A2Πu-X2Σ+g 带系的(3,1)、(4,2)、(5,3)、(8,5)带的谱线,其中(5,3)带是第一次被指认.利用测得的4个带以及文献中的14个带的谱线进行全局拟合,得到了一系列的分子常数(υA=0~9和υA=0~5).
