| Abstract: | A study has been made of the electronic absorption bands in the IR spectral region and the room-temperature magnetic susceptibility of polycrystalline layers and powders of nickel phthalocyanine after oxidation by halogen vapors. The polarization of the long-wave electronic band corresponds to the hypothesis of light absorption by conduction electrons. It has been shown that the magnitude of the magnetic susceptibility of the oxidized samples is independent of their degree of oxidation, and an explanation for this lack of dependence is given within the framework of Hubbard's model.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 5, pp. 534–539, September–October, 1989. |
