Abstract
A set of mass-independent U mj and Δ mj parameters globally describing vibration-rotation energy levels of the CO molecule in the X 1σ + ground electronic state was fitted to more than 19,000 transitions of 12C 16O, 13C 16O, 14C 16O, 12C 17O, 13C 17O, 12C 18O, and 13C 18O isotopologues collected from the literature. The maximal values of the vibrational V and the rotational J quantum numbers included in the fit was 41 and 128, respectively. The weighted standard deviation of the fit is 66. Fitted parameters were used for calculation of Dunham coefficients Y mj for nine isotopologues 12C 16O, 13C 16O, 14C 16O, 12C 17O, 13C 17O, 14C 17O, 12C 18O, 13C 18O, and 14C 18O. Calculated transition frequencies based on the fitted parameters were compared with previously reported. A critical analysis of the CO HITRAN and HITEMP data is also presented.
