Thermodynamic Functions of ArO and ArO+

Abstract

The vibrational-rotational partition functions and thermodynamic functions of ArO and ArO+ have been calculated in the temperature range of 298.15–10 000 K based on the interatomic interaction potentials. The formation enthalpies are found to be $${{\Delta }_{f}}H^\circ $$ (ArO, 298.15 K) = 243 ± 5 kJ mol–1 and $${{\Delta }_{f}}H^\circ $$ (ArO+, 298.15 K) = 1508 ± 5 kJ mol–1. The calculation results have been deposited into the IVTANTERMO database.
