β¦ Synopsis
The millimeter- and submillimeter-wave spectra of (\mathrm{CHF}{3}, v=0, v{3}=1,{ }^{13} \mathrm{CHF}{3}, \boldsymbol{v}=\mathbf{0}, \mathrm{CDF}{3}), (v=0, v_{2}=1, v_{3}=1), and ({ }^{13} \mathrm{CDF}{3}, v=0) have been observed and accurate rotational and centrifugal distortion constants have been derived from their analysis. The splitting of the (K=3) lines of (\mathrm{CHF}{3}) and (\mathrm{CDF}{3}) has been observed for high- (J) values and the splitting constant (h{3}) has been determined. The (J) dependence of the (h_{3}) coefficient was also pointed out. Β§ 1994 Academic Press. Inc.

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}=-18.1176
The ground state rotational spectrum of \(\mathrm{CH}_{3} \mathrm{CF}_{3}\) was measured from \(190 \mathrm{GHz}, J=18\), up to \(910 \mathrm{GHz}, J=87\) and \(K=63\). These measurements allow us to determine accurate molecular constants, including the three sextic centrifugal distortion constants:
The millimeter- and submillimeter-wave spectrum of the ground and \(v_{2}=1\) vibrational excited state of \(\mathrm{PF}_{3}\) has been observed and analyzed. A centrifugal distortion analysis of the spectra extended up to the octic terms allowed an accurate determination of the spectroscopic consta
