Variation in Symmetry Around Doped Pr(III) Ion in Saturated Solution of Medicinal Compounds with Reference to Judd-Ofelt Electronic Spectral Parameter

Abstract

The interaction of medicinal compounds with Pr(III) ion in the
form of doped model have been discussed in terms of covalency
(β) and Judd-Ofelt symmetry (T₄/T₆) parameters as derived from
f↔f  transitions. The doped model involves small concentration
of Pr(III) ion salt in saturated solution of medicinal compounds in
alcohol. The medicinal compounds include anthelminthic drugs,
viz., thiabendazole, piperazine, mebendazole, pyrantel pamoate,
albendazole, levamisole, diethylcarbamazine, antimicrobial drugs,
viz., sulfaacetamide, sulfadiazine, sulfaguanidine, sulfamethoxazole,
pefJoxacin, ciprofioxacin, tinidazole, metronidazole, atovaquone,
pentamidine and anti anginal drugs, viz., amIodipine, atenolol
and nifedipine. It also describes electronic spectral characterization
in terms of various parameters. The linear relationship between
oscillator strength (P) and VT₄/vT₆ has been discussed with reference
to hypersensitive transition, i.e., ³P₂ band of Pr(III) ion.
