    Measurement of intensities of some newly observed diagram lines in the L-emission spectra of 57La to 63Eu (1992)

    Notes: A method is described for the estimation of relative intensities of weak diagram lines from the microphotometer records of x-ray emission spectra registered on photographic films. The method is based on first correlating the experimentally determined relative intensities of two intense diagram lines with the theoretically calculated relative intensities. The experimental relative intensities of weak diagram lines are then interpolated to yield the corrected experimental relative intensities. These interpolated experimental relative intensities are found to be in good agreement with the theoretical relative intensities. The method has been applied to some recently reported weak lines in the L-emission spectra of the rare earth 57La to 63Eu.

    X-ray absorption near-edge study of some rare earth complexes (1993)

    Notes: The x-ray L3 absorption edges of all cis-1,2,3,4-cyclopentanetetracarboxylic acid complexes of Gd, Tb, Dy and Ho were recorded with the help of a 400 mm Cauchois-type bent crystal x-ray spectrograph. The behaviour of the four lanthanide cations in the environment of the same complexing ligand was investigated. The chemical shifts were correlated with IR studies. Information regarding bonding in these complexes was obtained from the observed chemical shifts. A regular decrease was observed in the average metal - ligand bond distances with increasing atomic number of the metal ion in these complexes and this is interpreted in terms of metal - oxygen interaction.

    X-ray K absorption studies on some cobalt thiosemicarbazones (1988)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The x-ray K absorption edges of Co in some thiosemicarbazones were recorded. The results are discussed qualitatively in terms of molecular symmetry and the nature of the ligand. The extended x-ray absorption fine structure associated with the K absorption edge of cobalt in these thiosemicarbazones was also studied. The average metalligand bond lengths in these complexes were calculated.

    XANES studies of some copper(II) mixed-ligand complexes in solid form and in aqueous solution (1995)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: X-ray K-absorption spectra of seven structurally important copper(II) mixed-ligand complexes were recorded using a 0.4 m radius Cauchois-type bent crystal x-ray spectrograph. The spectra of the complexes were recorded in both the solid and in aqueous solution. The observed x-ray parameters, e.g. chemical shifts, edge widths, shift of the principal absorption maximum and structure of the K-edge, were used to interpret the proposed structure of the complexes.
