EPR spectra of fullerene soot at the various oxygen content and composite PhC-2 + 3% fullerene soot. a. The magnitude of the pressure of residual atmospheres (from the small to the larger amplitudes of the EPR spectrum) at room temperatures of pumping out: 1; 0.8; 0.61; 0.42; 0.21; 0.1; 0.043; 0.02; 0.001 atm., *—pump. 0.5 h at 160 °C, dash line—fitting by 3 Lorentzian. The insert: the dependence of the total intensity of the EPR spectrum on the oxygen pressure. *—pumping out 0.5 h at T = 160 °C. b. The composite PhC-2 + 3% fullerene soot (FS) before (1) and after (2) pumping out of the samples during 1 h at T = 160 °C. Dashed lines—fitting (Table 1)
