Abstract
Phase separated structure of solvent swollen coal was characterized thorough its property of proton flip-flop spin diffusion. It is shown that the fashion of coal swelling is non-uniform on a segmental scale and a microscopic phase separation does take place on a scale from several to 20 nm even in good solvents like pyridine.
