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

摘要

The interaction of medicinal compounds with Pr(III) ion in the form of doped model have been discussed in terms of covalency (#beta#) and Judd-Ofelt symmetry (T_4/T_6) 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.,sulfaacetamidde,sulfadiazine,sulfaguanidine,sulfamethoxazole,pefloxacin,ciprofloxacin,tinidazole,metronidazole,atovaquone,pentamidine and antianginal drugs,viz., amlodipine,atenolol and nifedipine. It also describes electronic spectral characterization in terms of various parameters. The linear relationship between oscillator strength (P) and vT_4/T_6 has been discussed with reference to hypersensitive transition,i.e., ~3P_2 band of Pr(III) ion.
