Electronic Spectral Characterization of Pr(III) Systems Involving Some Analytically Important Reagents at pH-3 in Ethyanol Medium-Part-I

Abstract

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), ludd-Ofelt symmetry parameter (T₄/T₆), bonding
parameter (b^1/2) , Slater-Condon parameter (F₂, F₄, F₆), Racah parameter
(E¹, E², E³),  Lande parameter (ζ_4f),  percentage reduction in F₂ parameter
(% rF₂) and percentage reduction in ζ_4f  parameter (% rζ_4f). 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.
