Abstract

The aromaticity fa, crystallite parameters dm, dy, La, Lc, Mc, and RDF parameters r1 and Ka have been determined for sedimentary organic matter, such as kerogens, coals, and bitumens. Here, the rt value is the interatomic distance between the nearest neighbors of carbon atoms, and Ka is an empirical coefficient as an indicator of the degree of order-stacking for aromatic clusters. The refined methods of X-ray diffraction include the improved experimental conditions and new computer programs. The computer programs are composed of four software: AMORPHOUS software; NORMALIZATION software; RDF (Radial Distribution Function) software; and MPS (Multiple Peak Separation) software.
