【 摘 要 】

Studies on the difference in energy parameters and comparative absorption spectrophotometry involving 4𝑓-4𝑓 transitions on Nd(III) and glutathione reduced (GSH) in the absence and presence of Zn(II) have been carried out in aquated organic solvents (50 : 50) like methanol, dioxane, acetonitrile and dimethylformamide. Variations in the spectral energy parameters - Slater-Condon (𝐹𝐾) factor, Lande spin-orbit coupling constant (𝜉4𝑓), nephelauxetic ratio (𝛽), bonding parameter (𝑏1/2) and percent covalency (𝛿) - are calculated and correlated with binding of Nd(III) with GSH in presence and absence of Zn(II).
