The shape of the ESR spectra of powder samples of trimeric heteronuclear clusters is considered. The thermal population of two Kramers ground-state doublets is shown to lead both to a temperature-dependent effective molecular g value and a structured line shape. A detailed analysis of the ESR spectra of heteronuclear Cr2Fe- and CrFe2-carboxylates is presented. The antisymmetric exchange parameter is shown to be relatively small for the mixed carboxylates under consideration.
