Abstract:
The vibrational-rotational partition functions and thermodynamic functions of $\rm ArO$ and $\rm ArO^+$ have been calculated in the temperature range of $298.15$–$10000$ K based on the interatomic interaction potentials. The formation enthalpies are found to be $\Delta_fH(\rm ArO{,}\,298.15$ K$) = 243 \pm 5$ kJ mol$^{-1}$ and $\Delta_fH(\rm ArO^+{,}\,298.15$ K$) = 1508 \pm 5$ kJ mol$^{-1}$. The calculation results have been deposited into the IVTANTERMO database.
