Energy and intensity parameters

Theoretically calculated values of the following parameters: bonding parameters (b1/2), percentage covalency (δ), Nephelauxetic ratio (β), Slater-Condon (Fk), Racah energy (Ek), and Spin-orbit interaction (ξ4f) were employed to look into the insight of the complexation, further analysis with the intensity parameters, Judd-Ofelt Tλ (λ=2, 4, 6) and oscillator strengths (P) to explore the various 4f-4f transitions under varied conditions. Analyses based on the intensity parameter values for complexation at varied time intervals and temperatures clearly showed that the rates increased proportionately with temperature and time, validating the Arrhenius reaction rate.
