Covalency model of hypersensitivity

The covalent model of hypersensitivity was developed by Choppin and coworkers [70,74] to explain (i) the observed order of sensitivity of the parameters to the environment is 72 > 74 > 7f, >, (ii) the general trend of the hypersensitive transition oscillator strength increases with estimated covalency, (iii) the observed hypersensitivity in octahedral complexes, (iv) the simultaneous occurrence of hypersensitivity and large splittings of... [Pg.600]

Crystal field theory, intensities of 4f-4f transitions, Judd-Ofelt theory of electric-dipole transitions, covalency model of hypersensitivity, dynamic coupling mechanism, solution spectra, spectral data for complexes, solvent effects, fluorescence and photochemistry of lanthanide complexes are dealt with in spectroscopy of lanthanide complexes. [Pg.1000]

According to Judd and Ofelt, the hypersensitivity of a transition is due to the mixing of the excited states 4f" 1 —< 5d1 and 4f 1 5g1 with 4f" states. Henrie et al. added a partial charge transfer character to the above mixing of states in their covalency model in which... [Pg.605]
