TheJ= 1–0 rotational transition of14NF3has been measured at high resolution in a pulsed jet Fourier transform microwave spectrometer. The transition is split into three major components due to the nuclear quadrupole coupling constant of the14N nucleus; these in turn are further split into hyperfine components due to the fluorine spin–molecular rotation interaction. The improved values of the rotational and nitrogen quadrupole constants areA = B= 10681.0819(15) MHz and χcc(N) = −7.093(8) MHz. The newly measured spin–rotation and spin–spin constants areCF= 21.8 ± 1.6 kHz,CN= 2.4 ± 1.6 kHz, andDcc(F) = 17 ± 10 kHz. |
