A mass spectrometric study of nitrogen trifluoride provides data on the relative abundances and appearance potentials of the NF3+, NF2+, NF+, N+, F+, Fmdash;, and F2mdash;ions. The heat of formation of the NF3molecule is used to determine the probable processes of formation of the N+and F+ions and to calculate the ionization potentials of the NF and NF2radicals.
