Mössbauer spectra of Fe(Cr, Al)2O4 spinels are reported and interpreted using partial quadrupole splitting theory. Fe2+T site quadrupole splittings are calculated for different next-nearest neighbour configurations. Assuming random distribution of the Cr3+ and Al3+ in the octahedral M sites, good semiquantitative agreement between calculated and observed quadrupole splittings and absorption intensities is obtained.
