Abstract : The reaction between HTcO4 and MeOH in 13 M H2SO4 was investigated by 99Tc NMR, UV-visible and X-ray absorption fine structure (XAFS) spectroscopy. Experimental results and first principles calculations show the formation of Tc(+5) sulfate complexes. The results expand the fundamental understanding of Tc in high acid solutions.
