High-resolution ro-vibrational and rotational spectroscopy of HC₃O.

ABSTRACT: The ro-vibrational and pure rotational spectra of the linear ion HC₃O⁺ have been investigated in a 4 K cryogenic ion trap instrument. For this, a novel action spectroscopic technique, called leak-out-spectroscopy (LOS, Schmid et al., J. Phys. Chem. A 2022, 126, 8111), has been utilized and characterized. In total, 45 ro-vibrational transitions within the fundamental band of the ν₁ C-H stretching mode were measured with a band center at 3237.132 cm^-1, as well as 34 lines from the combination band ν₂ + ν₄, and 41 lines tentatively identified as the combination band ν₂ + ν₅ + ν₇, interleaved and resonant with ν₁.
