Abstract
The chemical structural characterization of four samples (M-1, M-5, VS, and BaS) from Southern China was studied by Raman spectroscopy with curve-fitting analysis. Several Raman parameters, e.g., full width at half maximum (FWHM) and intensity ratio (ID1/IG), were obtained. Vitrinite (VS) and barkinite (BaS) were separated from the same coal sample, separately. The results showed that nine bands were assigned from the Raman spectra. Two typical bands, G and D1, have broad peaks, which showed that all the samples have poor order in chemical structure. Barkinite has higher disorder in chemical structure than vitrinite.Entities:
