The values of Slater‐Condon (F 2 , F 4 , F 6 ) and Racah (E l , E 2 , E 3 ) interelectronic repulsion and Landé (ζ 4f ) parameters and electronic energy levels have been computed from the diffuse reflectance spectra of eight Nd 3+ complexes. Configuration interaction parameters (α β, Y(22, 1) and Y(22, 3)) have also been computed for the Nd 3+ aquo‐ion. The decrease in the F 2 values of the complexes as compared to the free ion is greatest among all the parameters. The bonding parameter b 1/2 has been computed from the observed nephelauxetic ratio. The relative variation of covalent bonding in the complexes has been discussed, the effects of the crystalline hosts on the F k and ζ 4f parameters have also been examined.
