4. Unequivocal assignment of the fullerene carbons of diethyl 1,2‐methano[60]fullerene 61,61‐dicarboxylate using 2D INADEQUATE NMR spectroscopy

Assignment of all carbons of the [60]fullerene sphere of diethyl 1,2-methnano[60]fullerene 61,61-dicarboxylate using 2D INADEQUATE NMR spectroscopy is described. Acquiring the INADEQUATE data with small spectral widths and optional F1 folding with States-TPPI phase implementation provides a convenient route to high-resolution data. A description of the topology of the [60]fullerene sphere and its comparison with x-ray crystallographic analysis is also presented. Copyright © 2001 John Wiley & Sons, Ltd.
