Abstract
Mössbauer spectrum of plumbo-jarosite mineral from Utah showed the presence of Fe(III) in a distorted octahedron. EPR investigations of the sample further confirmed that ferric iron is in a distorted octahedron. The optical absorption spectrum consists of a series of bands that can be assigned to spin-forbidden crystal field transitions of Fe(III) in octahedral coordination. © 1991.
