Szigeti Charge and Its Correlation with Hyperfine Coupling Constant of Doped Mn²⁺ Ion in Divalent Metal Compounds

Abstract

Correlations are given between Szigeti charge and the hyperfine constants of the doped Mn 2+ ion in the divalent metal compounds and of Cr + ion in the alkali halides respectively. From the correlations it is concluded that the deviation of Szigeti charge from the formal charge Z e relates to covalency. On this conclusion a hypothesis is introduced that Szigeti charge represents substantially the static charge of the constituent ion.
