All of the rotational spectral lines observed and reported in the open literature for 83 diatomic molecules have been tabulated. The isotopic molecular species, assigned quantum numbers, observed frequency, estimated measurement uncertainty, and reference are given for each transition reported. In addition to rectifying a number of misprints and errors in the literature cited, the spectral lines for approximately 20 molecules have been reanalyzed to produce a comprehensive and consistent analysis fo all the data extracted from various literature sources. The derived molecular properties, such as rotational contants, hyperfine structure constants, electric dipole moments, rotational g-factors and internuclear distances are listed with one standard deviation uncertainties for all species.
