    "abstract": "Rotationally resolved infrared spectra are reported for halogen atom - HF\nfree radical complexes formed in helium nanodroplets. An effusive pyrolysis\nsource is used to dope helium droplets with Cl, Br and I atoms, formed by\nthermal dissociation of Cl$_2$, Br$_2$ and I$_2$. A single hydrogen fluoride\nmolecule is then added to the droplets, resulting in the formation of the X-HF\ncomplexes of interest. Analysis of the resulting spectra confirms that the\nobserved species have $^2\\Pi_{3/2}$ ground electronic states, consistent with\nthe linear hydrogen bound structures predicted from theory. Stark spectra are\nalso reported for these species, from which the permanent electric dipole\nmoments are determined.",
