Abstract

The isolation of minor isomers of [84]fullerene (C₈₄), five in total, and their characterization by ¹³C NMR spectroscopy, have been reported for the first time. The vis-near-infrared absorption spectra for these isomers are also reported. The ¹³C NMR results indicate that the isolated C₈₄ isomers have, in order of decreasing abundance, C₂, C_s(a), C_s(b), D_2d(I), and D₂(II) molecular point group symmetry. In addition, we have found another C₈₄ minor isomer adjacent to C_s(b)-C₈₄ in the HPLC chromatogram.
