| Abstract: | Ro-vibrational spectrum of the (1, 4) band in the comet-tail system of CO+ cation is observed employing the optical heterodyne and magnetic rotation enhanced velocity modulation spectroscopy in the range of 13 189-13 472 cm−1. Two hundred and eighteen spectral lines are assigned to 12 branches of this band for the first time, thus, precise molecular constants of the levels involved are obtained by nonlinear least-squares fitting procedure combining with our previous spectrum of the (1, 2) band. |
