Acylium- and thioacylium ions, R-CO+ and R-CS+, are classes of astrochemically relevant molecular ions that have received relatively little attention from molecular spectroscopy so far. Triggered by recent laboratory and astronomical observations of the polyatomic HC3O+, HC3S+, and CH3CO+ species (see, Thorwirth et al. 2020, Cernicharo et al. 2021 and references therein) our laboratory investigations have now been extended towards other selected (thio)acylium species. Here, we would like to present a status report on our studies performed using various action spectroscopy schemes in combination with state-of-the-art ion traps.
