The glow discharge at low pressure, under nitrogen atmosphere, is an easy method to synthesize nitrogen encapsulated fullerenes. We present here the results concerning our attempts to optimize the synthesis conditions by this method as well as basic characterization of the obtained products, namely N@C-60 and N@C-70 together with the molecular counterparts N2@C-60 and N2@C-70. Changes in pressure, voltage discharge and temperature indicated the optimum yield for N@C60 in our case, which was about 0.0025%, was obtained at 650 degrees C, 1 Torr, 850 V and I to 2 mA discharge. In this paper we discuss the HPLC separation of these products and the behavior of N-2 in the C-60 cage.
