Electron spin resonance of Mn²⁺ ions in matrices of polycrystalline samples of Zn₄O[(CH₃)₂CHCOO]₆ and Zn₄O[(CH₃)₃CCOO]₃

The ESR spectra of polycrystalline samples of Zn4O[(CH3)2CHCOO]6 and Zn4O[(CH3)3CCOO]6, activated by Mn2+ ions at various concentrations, were investigated. An analytical theory was developed for the contour of the hyperfine components of the permitted and various types of “forbidden“ transitions. On the basis of the obtained magnetic-resonance parameters conclusions were reached about the local symmetry and coordination of the Mn2+ ion in the investigated compounds.
