Abstract:Following-up on our recent infrared photodissociation (IRPD) spectroscopic detection of the linear Ne-tagged HC$_3$O$^+$ molecular ion,\footnote{S. Thorwirth, M. E. Harding, O. Asvany, S. Brünken, P. Jusko, K. L. K Lee, T. Salomon, M. C. McCarthy, and S. Schlemmer 2020, Mol. Phys. 118, e1776409} the C-H stretching mode $\nu_1$ of bare HC$_3$O$^+$ has now been studied at high spectral resolution. The spectrum was observed using a 4~K cryogenic ion trap apparatus at Cologne (COLtrap) and a cw optical parametric oscillator using the method of laser-induced inhibition of complex growth (LIICG) with helium as tagging agent. Fifteen rotational-vibrational transitions were observed, covering $P(8)$ to $R(6)$. The band origin is found at 3237.1\,cm$^{-1}$ and hence blueshifted by some 5\,cm$^{-1}$ compared to that of the HC$_3$O$^+-$Ne weakly bound complex probed earlier in the IRPD study.
