Charge-transfer Absorption Intensity and Magnetic Property of Solid Ion Radical Salts

Abstract

Abstract The electronic spectrum of solid ion radical salt is known to be different from the monomer spectrum of the radical ion and to show an intermolecular charge-transfer transition between ion radicals in the low-energy region. The intensity of the charge-transfer absorption was theoretically obtained by applying one-dimensional half-occupied Hubbard model to the segregated stack of ion radicals of solid ion radical salts. The intensity of the charge-transfer absorption was then correlated to the magnetic properties of those solid ion radical salts.
