Electronic Spectral Parameters of the Saturated Solutions of Some Amino Acids and Some Bioactive N-Heterocyclic Compounds Doped with Pr(III) Ion

Abstract

Electronic spectral parameters,  viz., Judd-Ofelt parameter (T_λ),
Racah (E^k), Slater-Condon (F^k),  Lande (ζ_4f) and bonding parameters
( β ,b^1/2 and δ ) have been evaluated for the saturated solutions of some
amino acids (L-cystine, L-Ieucine, L-proline, L-threonine, arginine,  β-alanine
and DL-aspartic acid) and some bio-active N-heterocyclics (indole,
4-aminoantipyrine, 1,2,3-benzotriazole and uracil) doped with Pr(III)
ion. The change in symmetry around Pr(III) ion and covalency in M-L
interactions is observed. A linear relationship between oscillator strength
(P_ed) and  vT₆ has beeen observed for hypersensitive transition
(³H₄ →³P₂).
