64.パルス^1H-NMRによる膨潤炭の相分離構造の解析

抄録

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 in the segment scale and a microscopic phase separation does take place in a scale from several to 20nm even in good solvents like pyridine.
