| Abstract: | By using CP, MAS, TOSS, and Dipolar Dephasing Techniques, the nonproto-nated carbons can been distinguished from a solid-state ~(13)C NMR spectra. Themethod presented is an effective tool for determining the amount and type ofindividual carbon atoms in the natural complex polymers, such as coal, kerogenetc. |
