Abstract:
The ultraviolet and visible absorption spectra of 1,5-diphenylformazan and its nickel complex in acetone, ethanol, and carbon tetrachloride have been calculated. For a qualitative interpretation of the spectrum, the calculations for the molecules of the complex and the ligand were carried out by the MO LCAO method in the Mulliken-Helmholz-Wolfsberg approximation. According to the results obtained the oscillator strengths of the transitions in the spectrum of the complex decrease as the interaction of the solvents with Ni increases in the order CCl4, C2H5OH, C3H6O. This leads to a decrease in the negative charges on the nitrogen atoms and a decrease in the oscillator strengths of the transitions between the MO including the AO of nitrogen. All the transitions are interpreted as π-π* transitions.
