✦ Synopsis

The milimeter-wave, submillimeter-wave, and FIR spectra of the ground state of (\mathrm{CHF}{3}) have been observed and analyzed up to (J=78). The resulting spectroscopic constants are: (B{0} / \mathrm{MHz}=) (10348.8706(2), D_{j} / \mathrm{kHz}=11.34482(13), D_{J K} / \mathrm{kHz}=-18.11765(50), H_{J J} / \mathrm{Hz}=0.020069(24)), (H_{J N} / \mathrm{Hz}=-0.08598(10), H_{\kappa K j} / \mathrm{Hz}=0.11372(27), L_{J} / \mathrm{mHz}=-0.669(16) \times 10^{-4}, L_{J \mathcal{J}} / \mathrm{mHz}) (=0.4953(80) \times 10^{-3}, L_{J K} / \mathrm{mHz}=-0.1189(17) \times 10^{-2}), and (L_{J K K} / \mathrm{mHz}=-0.1115(31) \times) (10^{-2}). The splitting of the (K=3) ground state lines has been observed starting from the (J=29 \leftarrow) 28 transition and the determined values of the splitting constants are (h_{3} / \mathrm{Hz}=0.29689(45) \times) (10^{-2}) and (\delta h_{3} / \mathrm{Hz}=-0.2054(52) \times 10^{-7}).
