Separation and spectroscopy of fullerenes

The chromatographic procedure which led to isolation of the first pure samples of C60 and C70, together with recent advances in the separation of higher fullerenes, are described. At least three isomers of C78 exist. Structural features contributing to the stability differences between fullerenes are discussed. 13C NMR, UV, IR, Raman and neutron scattering/diffraction measurements on C60 and C70 are summarized and reviewed.
