Spectrophtometric Characterization of doped Pr(III) Ion in Sarurated Alcoholic Solution of Some Thiosemicarbazone derived from Carbonyl Compounds

Abstract

The stereo-environment of doped Pr(III) ion in saturated solution
of some thiosemicarbazones of carbonyl compounds in alcoholic
media has been discussed on the basis of various electronic spectral
parameters. The various electronic parameters, viz., Judd-Ofelt intensity
parameter, (T_λ) Slater-Condon (F_k), Lande's (ζ_4f) intensity
of hypersensitive band (³P₂) and Racah's (E_k) as well as bonding
parameter b^1/2 for Pr(III) ion doped in alcoholic saturated solution
of thiosemicarbazones derived from thiosp,micarbazide and ethyl
vanillin, 3,4-dirnethoxy benzaldehyde, 2,5-dimethoxy benzaldehyde,
chalcone, p-hydroxy acetophenone, benzophenone, 3-nitrobenzaldehyde
and 4-arnino acetophenone etc.
