Popis:	This feasibility study allowed us to establish three main results: (i) With high quality XANES spectra, it becomes quite possible to resolve the characteristic σ*(S-S), π*(S-S) and σ*(S-C) resonances; (ii) The undulator gap scan technique can yield excellent EXAFS spectra at the sulfur K-edge over more than 1300 eV; (iii) S K-edge EXAFS spectra made it possible to discriminate between vulcanizates with variable amounts of sulfur crosslinks and zinc sulfide.
