Electron spin resonance of isolated coal macerals: preliminary survey

Journal Article · · ACS Symp. Ser.; (United States)
Electron spin resonance determinations of g-values, linewidths, radical densities and saturation properties have been performed on carbon radicals in samples of coal macerals isolated by density gradient centrifugation techniques. These data are compared with elemental analyses and density measurements. Each maceral type exhibits a different ESR signature which can be understood in terms of the nature of the starting organic and the extent of coalification. 13 references, 9 figures, 1 table.
