Studies of the kinotics of hydrogen atom reactions with $NCl3$ and with $NFCl2$ performed in our laboratory demonstrated the production of excited state nitrenes in these $systems.\ast$ The time profiles of the NX emissions are consistent with a two step mechanism involving the formation of $NX2$ and NXY intermediates (X, Y = halogens), a class of radicals for which there is almost no spectroscopic information available in the literature. Investigations of the spectroscopy of low temperature matrix isolated $NX2$ and NXY radicals, prepared by reacting fluorine atoms with the corresponding $NX3$ (or $NX2Y$) before deposition, are reported.
