摘要: Abstract The excited triplet states of a series fullerene C 60 mono- and bis-adducts have been studied using high-frequency (240 GHz) TR-EPR spectroscopy. simulation the spectra gave zero-field splitting parameters population ratio sublevels. Moreover, thanks to increased spectral resolution available at very high frequencies, g tensor principal values directions with respect ZFS axes were determined. effect number, position nature substituents on is discussed. For some adducts signal decay was analysed.
