Studies of the dependence of electron spin resonance on heat treatment temperature were carried out for coal carbons made from coals of various rank. The absorption curve of coal carbons changes from Gaussian type to Lorentzian type, the line width decreases and reaches a minimum, and the spin cente

13C cross-polarization and magic-angle spinning (CP/MAS) nuclear magnetic resonance (n.m.r.) experiments are reported on two fusinites, three vitrinites, one micrinite, one sample of attrite, one exinite, one resinite and one lignite. With one exception, the maceral spectra show no more fine structu
