| 摘 要： | 用一束波长为230.1 nm的激光, 通过(2+1)共振增强多光子电离(REMPI)过程激发超声射流冷却的CO分子制备处于基电子态X2∑+的CO+离子, 随后引入另一束可调谐激光将CO+离子激发至A2∏1/2,3/2态, 利用光电倍增管(PMT)检测发射的荧光信号强度随激发光波长的变化, 分别在487-493 nm和453-459 nm波长范围内获得了CO+离子A2∏1/2,3/2←X2∑+电子态跃迁(0,0)和(1,0)带的激光诱导荧光(LIF)激发谱.

| Abstract: | The laser induced fluorescence (LIF) excitation spectrumof molecular ions in cooperating with resonance-enhanced multi-photon ionization (REMPI) process was demonstrated with CO+ ions. The CO+ ions at the ground X2∑+ state were prepared by (2+1) REMPI of supersonically cooled COmolecules at 230.1 nm, and the rovibronically resolved LIF spectra of CO+(A2∏1/2,3/2←X2∑+) were measured by scanning another laser in the range of 487-493 nm and 453-459 nm, which belong to (0,0) and (1,0) bands, respectively. |
