XANES spectroscopic studies at L3 edge of 79Au in its various chemical forms

The systematic X-ray absorption near edge structure (XANES) investigation at Au L3-edge was made on Au in metallic form and its compounds in various definite oxidation states, viz., Au(OH)3, AuCl, AuCl3, HAuCl4, AuI and AuBr3. The spectra have been recorded with linearly polarized photon beam from 2.5 GeV INDUS-2 Synchrotron source. All XANES spectra were deconvoluted to configure the energy positions of bound and continuum state transitions....
