Abstract
The enthalpies, entropies, and free energies of CO in the ground state have been computed statistically in the temperature range 100-$-5000^\circ K$ at $50^\circ$ intervals, with aid of the spectroscopic data obtained by Rank et $al.^{1}$ The effect of the anharmonicity and centrifugal stretching has been introduced. The influence of nuclear spin has also been included, and the electronic contribution tentatively neglected. The following values are obtained: [FIGURE] For comparison, calculations were carried out also by the harmonic oscillator-rigid rotator approximation. These results will be of aid not only in the usual physical and chemical problems, but also in the field of astronomy.
