The Nephelauxetic Effect — Calculation and Accuracy of the Interelectronic Repulsion Parameters

Abstract: Expressions are reviewed which may be used to determine 10 Dq and B from the spin-allowed bands in the optical spectra of d 3 and d 7 electron systems within octahedral and tetrahedral sym metry. Application to low-temperature single crystal spectra demonstrates that (i) the semi-empirical ligand field theory reproduces transition energies with sufficient accuracy; (ii) differences in the values of 10 Dq and B observed with different fitting methods may be attributed to the inaccuracy of experimental data; (ii… Show more

“…Generally two rather than three spin-allowed bands are observed, since the transition to 4 A 2 g(F) level is very weak [26]. In Pyrazolone-based Schiff base 2393 We have used these bands to compute ligand field and repulsion parameters from equations [27,28]:…”

“…In 2 ], 2 band is obscured; (a) was used to calculate 2 , 10D q , and B 35 [27,28]. The magnitude of B determined for all complexes may be compared with that for free Co(II) ion (971 cm À1 ).…”
