The chloroniumyl cation, HCl$^+$, has been recently identified in space from Herschel’s spectra. A joint analysis of extensive vis-UV spectroscopy emission data together with a few high resolution and high accuracy mm-wave data provided the necessary rest frequencies to support the astronomical identification. Nevertheless, the analysis did not include any infrared vibration-rotation data. Furthermore, with the end of the Herschel mission, infrared observations from ground may be one of the few available means to further study this ion in space. In this work we provide a set of accurate rovibrational transition wavenumbers as well as a new and improved global fit of vis-UV, IR and mm-wave spectroscopy laboratory data, that will aid in future studies of this molecule.
