摘要: The Dunham parameters of the ground state CO molecule are determined by a least squares fit recent high-quality microwave and heterodyne frequency measurements. It is shown that these new more accurate than others obtained recently. Revised equilibrium molecular constants have been deduced from mass-scaling coefficients Guelachvili et al. most important ωe = 65 047 645(7) MHz, x e 398 365·1(14) y 312·11(14) B 57 907·98(6) αe 524·791(13) D 0·183 520 8(57) MHz R 1·128 243(1) A. allow precise determination transition frequencies, which can now be used as secondary standards in infrared ranges.
