Twenty-seven ΔJ = +1 rotational transitions for the HI-HF complex were observed in the 8-18 GHz frequency range. The lines were measured 10 an accuracy of 5 kHz using a pulsed-beam Fourier transform microwave spectrometer. The spectroscopic constants obtained by fitting the observed transitions are 21(B + C) = 2220.74746(82) MHz DJ = 8.842(32) kHz eqQ = 687.012(26) MHz and Δ(eqQ) = -40.6(2.6) kHz.
