摘要：

The carbon-rich molecular ions C3H+ and HC3O+ have been studied for the first time at high spectral resolution in the 5 mu m wavelength regime employing leak-out spectroscopy of their v2 (C3H+) and v3 (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.
