Abstract
Transient EPR spectroscopy has been applied to measure the spectra of excited triplet states in two series of fullerene bisadducts. Eight di fferent bisadducts of C-60 with bis(ethoxycarbonyl)methylene and five bis-N-methylpyrrolidines have been analyzed. The D and E parameters of electron dipolar interaction and the populations of the zero field tr iplet sublevels, accounting for spin polarization, have been determine d by spectrum simulation. They appear peculiar for each bisadduct. It is shown that triplet EPR technique represents a useful spectroscopic tool that allows structural assignments to bisadducts of C-60.
