Abstract (in english)
   Four Czech coals and their maceral fractions were characterized and studied from point of view of chemical structure. The oxygen, sulfur and nitrogen functionalities of maceral fractions of the coals were determined by the instrumental methods (DRIFTS-PLS, XPS). Also solid-phase NMR parameters were determined. On the basis, models of chemical structure of coal fractions were constructed and energies of these structures were calculated by computational chemistry methods. Moreover, the influence of oxygen on technological parameters of coal was described and discussed
