Abstract

Near-infrared magnetic circular dichroism studies of bovine liver catalase and heme octapeptide from equine cytochrome c indicate high-spin character for the former and mixed-spin character for the latter. It is suggested that the ligand-field strength of phenolate is roughly comparable with that of water and hydroxyl anion.
