Molecular structure characterization of middle-high rank coal via 13C NMR, XPS, and FTIR spectroscopy
ABSTRACT: Elemental analysis, nuclear magnetic resonance carbon spectroscopy (13C-NMR), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) experiments were carried out to determine the existence of aromatic structure, heteroatom structure and fat structure in c...
