A study of the vacuum-ultraviolet (VUV) fluorescence spectroscopy of NF$$_3$$ in the 11-30 eV range is presented. Synchrotron radiation from BESSY1, Berlin provides the VUV excitation source. Emission due to NF b $$^1\Sigma^+$$ - X $$^3\Sigma^-$$ at 528.8 nm is observed between 11.5 and 21.0 eV. Other emissions, which are believed to be due to transitions between highly excited states of NF$$_2$$, are observed at higher energies, 14.8-24.5 eV. Lifetimes associated with two of these bands at 325 nm and 410 nm are determined to be 12.9 and 13.0 ns, respectively. The similarity of the measured values implies that the two transitions originate from a common upper state.
