Abstract: The ligand field spectra of the complexes with formulae CoL₂'X₂ (L' = 1-methyl-3, 4-diphenylpyrazole, X=Cl^-, Br^-, I^-, NCS^-) and CoL₂Cl₂(L=1-methyl-3,5-diphenylpyrazole) have been fitted by means of Angular Overlap Model (AOM).The fitting results are comparatively satisfactory.The effects of varying the angle, the angle between the C₂ axis and the metal-ligand bond directions, on the energy levels of quartet states for the complex CoL₂Cl₂ were interpreted by means of AOMcalculations.The AOMparameters for each ligand were obtained.The fitting and calculating results has been discussed.

Key words: Pyrazole species complexes, Angular Overlap Model, Ligand field spectra
