Abstract:Infrared signatures of three molecular ions of relevance to the interstellar medium and planetary atmospheres_x000d_ have been detected at the Free Electron Laser for Infrared eXperiments, FELIX, at Radboud University (Nijmegen, The Netherlands) _x000d_ in combination with the 4K FELion 22-pole ion trap facility. Mid-infrared vibrational modes of protonated tricarbon monoxide, HC$_3$O$^+$, _x000d_ protonated vinyl cyanide, C$_2$H$_3$CNH$^+$, _x000d_ and protonated ethyl cyanide, C$_2$H$_5$CNH$^+$, were detected using resonant photodissociation of the respective Ne-complexes by monitoring _x000d_ the depletion of their cluster mass signal as a function of wavenumber. The infrared fingerprints compare very favorably_x000d_ with results from high-level quantum-chemical calculations performed at the CCSD(T) level of theory.
