โฆ Synopsis
The ground state rotational spectrum of As 35 Cl 3 was investigated in the range 120-376 GHz, and sextic-level spectroscopic constants were determined. A careful analysis of the observed splittings allowed the determination of the h 3 splitting constant, of the arsenic electric and magnetic hyperfine constants, and, notably, of the chlorine quadrupole coupling constant.

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 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
