✦ Synopsis

Two dominant electron paramagnetic resonance (EPR) hyperflne patterns for both La and Y fullerenes have been identified and linked to the mass spectroscopic (MS) peaks of La@& and Y @t& respectively, as also observed by Suzuki et al. Additionally, lower intensity La@C, EPR multiplets are identified which have not, as yet, been correlated with specific MS peaks. The intensity ratios of the two dominant EPR multiplets depend on various parameters such as solvent and temperature, suggesting the species possess different chemical properties.
