Isolation and Characterization by 13C NMR Spectroscopy of [84]Fullerene Minor Isomers

摘要: The isolation of minor isomers [84]fullerene (C84), five in total, and their characterization by 13C NMR spectroscopy, have been reported for the first time. vis−near-infrared absorption spectra these are also reported. results indicate that isolated C84 have, order decreasing abundance, C2, Cs(a), Cs(b), D2d(I), D2(II) molecular point group symmetry. In addition, we found another isomer adjacent to Cs(b)-C84 HPLC chromatogram.
