Figure 7From: Local structure and paramagnetic properties of the nanostructured carbonaceous material shungite The ESR spectra of the Sh-II-1 sample. 1 – initial, 2 - after annealing at Tann = 310°C during 1 h. Dotted lines are theoretical description of Dyson lines origin from conducting electrons. ν = 9,389.75 MHz.Back to article page
