✦ Synopsis

The absorption spectra of C6o and C7o undergo dramatic changes from a neat toluene solution to a neat triethylamine (TEA) solution. It is shown that the observed spectral changes are due to the bleaching of the C6o and C7o monomer absorptions and the absorption contributions of fullerene-TEA reaction products, not due to C6o (C7o)-TEA complexes. Dependencies of the chemical reactions on TEA concentration and time are examined. The electron transfer quenching of C6o and C7o monomer fluorescence intensities at low TEA concentrations is discussed.

Resonant electron capture by C 60 and C 70 was studied and it was established that long-lived (i.e. mass spectrometrically observable) parent negative ions are formed within an extremely broad energy region (0-14 eV). It has been shown that effective yield curves of C 60 -and C 70 -in the thermal en
