To investigate the intrinsic reactivity of atomic nitrogen, which had previously been accomplished only by examining its decay in the gas phase using special equipment, a nitrogen atom was inserted into a series of molecule‐encapsulating C 60 and C 70 fullerenes. Among the studied endofullerenes, H 2 @C 70 was able to encapsulate an additional nitrogen atom within the fullerene cage under radiofrequency plasma conditions. The product was analyzed by ESR spectroscopy and mass spectrometry in solution, which revealed that the nitrogen atom with a quartet ground state does not react but weakly interact with the H 2 molecule, thus demonstrating the utility of such fullerenes as “nanoflasks”.
