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.

Key words: CO+ ion, Laser-induced fluorescence, Jet-cooled
