Spectral Analysis of 4f-4f Transitions for the Interaction of Nd(III) with L-Histidine in the Presence and Absence of Zn(II) in Different Organic Solvents | Chapter 10 | Challenges and Advances in Chemical Science Vol. 7

 Using their absorption spectra as a probe, various parameters such as percent covalency (), the Slater-Condon (FK), the Nephelauxetic ratio (), bonding parameters (b1/2), and Lande orbit-spin coupling (4f) have been determined for the Nd(III)-L-histidine complex. The influence of the Zn(II) ion in the complexation was examined using a variety of solvents, including acetonitrile, DMF, methanol, and dioxane. The changes in these parameter values reflect and reveal the development of a connection between L-histidine and Nd (III). In comparison to the other solvents tested, the bond formation confirms that the DMF solvent boosts the 4f-4f dipole electric intensities. The electronic dipole transition is given by the Judd-Ofelt parameter, T ( = 2,4,6), and theoretical calculations have been performed to obtain the oscillator strength for Nd(III) complexation with L-histidine in the presence and absence of Zn(II) in various organic aquated solvents, such as acetonitrile, 1,4-dioxane, N,N-dimethylformamide(DMF), and methanol.
