Abstract: | The wavelengths of transitions in electronic absorption spectra of verdazyl radicals, the corresponding cations, and leuco compounds were calculated in valence and -electron approximations with allowance for configuration interaction. It was shown that the longest-wave bands in the investigated compounds are due to * electron transitions. The effect of the nature of the substituents on the position of the bands in the spectrum is discussed.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 22, No. 4, pp. 473–477, July–August, 1986. |
