Electronic spectral characterisation of Pr(III) systems involving some analytically important reagents at pH-3 in ethanol medium- Part-I

An electronic spectral investigation of some analytically important compounds with Pr(III) ion in the form of doped model have been discussed in terms of covalency (β), Judd-Ofelt symmetry parameter (T4/T6), bonding parameter (b1/2), Slater-Condon parameter (F2, F4, F6), Racah parameter (E1, E2, E3), Lande parameter (ζ4F), percentage reduction in F2 parameter (% rF2) and percentage reduction in ζ4F parameter (percentage rζ4f). The linear relationship between oscillator strength (P) and vT4/vT6 has been discussed with reference to hypersensitive transition, i.e., 3P2 bands of Pr(III) ion. (author)
