Abstract：The molecular cation CO+ is a very important transient molecular radical, and the spectra of the ion has been investigated by numerous researchers.Optical-heterodyne-magnetic-rotation-enhanced velocity modulation spectroscopy(OH-MR-VMS) was employed to measure the comet-tail system (A2Πi-X2Σ+) of 12C16O+ molecular ion.The vibrational rotation absorption spectra were observed in the near-infrared region, including three bands of (0，3)，(1，4)and(3，6).A set of precise molecular constants for the A2Πi(ν′＝0，1，3) were determined using the least-squares fit.This experiment has further proved that OH-MR-VMS is very valuable in measuring absorption spectra of molecular ions.
