Abstract
The carbon-rich molecular ions C3H＋ and HC3O＋ have been studied for the first time at high spectral resolution in the 5μm wavelength regime employing leak-out spectroscopy of their ν2 (C3H＋) and ν3 (HC3O＋) vibrational fundamentals. All measurements were performed in a newly built cryogenic 22-pole ion trap apparatus, the COLtrap II instrument. Besides the action spectroscopic characterization the new measurements have also been used towards optimization and an improved understanding of the leak-out process via a semi-quantitative kinetics model for which some rates are determined or estimated and rationalized.
