Sv. Chernov et al., X(ALPHA)-SW CALCULATION OF THE XANES SPECTRA OF MOLYBDENUM IN NIMOO4 AND MOO3 CRYSTALS, Journal of structural chemistry, 36(6), 1995, pp. 918-924
Disadvantages of the modeling of the nearest crystal environment by a
traditionally charged cluster for an atom with essentially covalent bo
nds are demonstrated by a comparison between the numerical and experim
ental XANES absorption spectra of molybdenum in NiMoO4 and MoO3. A mod
el of boundary conditions is proposed which allows adequate calculatio
n of the covalent character of bonds in terms of the SCF-X(a)-SW metho
d The oxygen environment of molybdenum in NiMoO4 is determined.
