The J = 1 → 0 transition in CF3H and CF3D was observed using a molecular beam maser spectrometer. Typical resonance linewidths were 6 kHz (F.W.H.M.). Hyperfine structure due to deuterium quadrupole coupling, spinrotation and spin-spin interactions was resolved. The strength of the deuterium quadrupole coupling along the bond axis is eqQ = 170.8 ± 2.0 kHz. Fluorine and hydrogen spin-rotation interaction strengths were obtained.
