Exploring the Thermodynamic Characteristics of Isoelectronic Diatomic Interstellar Molecular Species: Oxygen- and Sulphur-containing Species

Article scientifique 2023 Anglais

Résumé

Abstract We studied the thermodynamic properties of 18 isoelectric diatomic interstellar molecular species (known and potential) containing oxygen and the corresponding isoelectronic atom; Sulphur, by providing a comprehensive data set for these molecules of astrophysical importance. We began this by computing its partition function q with the GAUSSIAN 09 suite of programs, the thermodynamics properties such as the entropy S, internal energy U, free energy F, heat capacity H etc. were derived. We showed the isoelectronic effect of these Sulphur and Oxygen containing molecular species on several interstellar molecules at temperatures ranging from 0K to 2×106 K (i.e., from the coldest place in the universe to the mean temperature of the interstellar medium).
