cds-question@unistra.fratomic-physicsspectroscopyPotential energy curves (PECs), transition dipole moments (TDS), spectroscopic constants, and spin-orbit coupling (SOC) matrix elements for eight doublet and two quartet states of the sulfur monoxide cation were calculated using the multireference configuration interaction (MRCI) method. Furthermore, the PECs of the Furthermore, the PECs of the The X2Pi and A2Pi potential energy curves were refined by fitting to the experimentally measured vibrational energy levels. Based on these data, the absorption cross sections arising from the A2Pi-X2Pi transition within the 30000-50000cm^-1^ range were simulated, and a comprehensive spectral analysis was performed. Moreover, the absorption cross sections for a total of six transitions were computed to simulate the absorption spectra of SO+ in cosmic atmospheres. It is expected that the spectroscopic data presented in this work will facilitate the characterization of exoplanet atmospheres in future observational missions. higher-lying electronic states.2026A&A...713A.107Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/713/A107CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/713/A107https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/713/A107http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/713/A107https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/713/A107https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/713/A107http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/713/A107GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/713/A107/table4Remaining spectroscopic constantsrecnoRecord number assigned by the VizieR team.
