An EPR (electron paramagnetic resonance) signal was detected in C{sub 60} powder (10{sup {minus}4} radical-to-C{sub 60} ratio) and studied by multifrequency (S-, X-, and Q-band) EPR using loop-gap resonators. The signal intensity is dependent on O{sub 2} as demonstrated by spectra recorded from N{sub 2}/O{sub 2} gas flow experiments, vacuum-evacuated (10{sup {minus}4} Torr) C{sub 60} samples, and C{sub 60} heated in air at 250 {degrees}C. 22 refs., 4 figs.
