✦ Synopsis

The J Å 1-0 rotational transition of 14 NF 3 has 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 the 14 N 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 are A Å B Å 10681.0819(15) MHz and x cc (N) Å 07.093(8) MHz. The newly measured spin-rotation and spin-spin constants are C F Å 21.8 { 1.6 kHz, C N Å 2.4 { 1.6 kHz, and D cc (F) Å 17 { 10 kHz.
