The Upper Freeport coal's components fractionated by solvent extraction were studied by X-band ESR spectroscopy. The pyridine soluble and acetone soluble components dissolved in NMP show an organic radical peak in frozen solution. Powder patterns are broader and anisotropic. Their spectra were simulated with a Lorentzian or Gaussian lineshape. The difference might come from the magnetically symmetric reorientation in solution and the magnetically asymmetric layering by packing effect in powder.
