摘要：
Using multi-step High Performance Liquid Chromatography (HPLC) it was possible to prepare a chromatographically pure sample of N@C-60. Invoking EPR spectroscopy of solid samples prepared after each HPLC step, the increase of relative N@C-60 concentration could unambiguously be determined. The UV/Vis spectrum of N@C-60 is indistinguishable within experimental error from that of C-60, confirming negligible coupling between nitrogen in its atomic ground state and C-60 cage molecular wave functions.
