We report the observation of the (0, 11, 0), (0, 20, 0), and (0, 00, 2) states of the weakly bound complex ArHF by direct far infrared absorption spectroscopy in a jet. A simultaneous analysis of all observed rovibrational frequencies has been conducted, and spectroscopic constants sensitive to the global topology of the intermolecular potential energy surface are given.
