The rovibrationally resolved Fourier transform (FT) far infrared (FIR) spectra of two intermolecular librations of (HF) 3 , namely the in-plane  6 and out-of-plane  4 bending fundamentals centered respectively at about 494 cm -1 and 602 cm -1 ,have been measured for the first time underjet-cooled conditions using the supersonic jet of the Jet-AILES apparatus. The simultaneous rotational analysis of 245 infrared transitions belonging to both bands enabled to determine the ground state (GS),  6 and  4 rotational and centrifugal distortion
