采用光外差磁旋转增强速度调制技术，在12100 ~ 14100cm−1近红外波段高分辨率地研究了O2+的第二负（A2Πu-X2Πg）体系。首次观测到3个新的热带（2,18）、（4,40）和（6,20）。通过对线位置的旋转分析，确定了所涉及状态的精确分子常数，精度为0.0028cm−1。
The second negative (A2Πu–X2Πg) system of O2+were investigated in the 12100–14100cm−1near infrared region at high resolution by employing optical heterodyne magnetic rotation enhanced velocity modulation technique. Three new hot bands (2, 18), (4, 40) and (6, 20) were observed for the first time. From the rotational analysis of the line positions, precise molecular constants of the states involved were determined with an accuracy of 0.0028cm−1.
