✦ Synopsis

Millimeter-wave and submillimeter-wave spectra of the rotational transitions in the (v_{2}=1) and (v_{5}=1) vibrational states of ({ }^{13} \mathrm{CH}{3} \mathrm{~F}) were measured up to (462 \mathrm{GHz}). Far-infrared spectra of these transitions were measured in the region (30-65 \mathrm{~cm}^{-1}) with a resolution of (0.0019 \mathrm{~cm}^{-1}) using an interferometric spectrometer Bruker IFS 120 HR. Almost 700 lines including 14 lines of the (\Delta\left(k-l{s}\right)= \pm 3) perturbation-allowed transitions in the (v_{s}=1) state were assigned. Both vibrational states are strongly perturbed, especially by the (x, y)-Coriolis resonance and "2, -1 " 1 -type interactions. The corresponding spectroscopical parameters were determined by a nonlinear leastsquares fit to the experimental data. (c) 1994 Academic Press, Inc.
