摘要: Abstract The difficulties associated with obtaining quantitative results from 13C nuclear magnetic resonance spectroscopy are discussed. By careful choice of the experimental conditions have been obtained for a mixture model compounds, containing most types carbon linkages present in coal-derived materials, and an aromatic fraction coal extract.
