Summary:Endohedral N@C 60 (atomic nitrogen inside C 60) is produced by ion implantation. N@C 60 is soluble in organic solvents and stable in air. A special feature is that it gives a very clear hyperfine split EPR signal with sharp lines even in the solid. This makes it an ideal probe for monitoring chemical reactions of C 60 via changes of the EPR signal. As an example, the formation of the monoadduct of diethyl malonate on C 60 will be discussed. In general, N@C 60 can be used as a probe or tracer for monitoring reactions or the transport of C 60. We show that C 60 is an ideal trap for atomic nitrogen. Nitrogen is in the center of C 60 and keeps its atomic structure. In a first experiment, the vibrations of nitrogen in C 60 were studied.
