摘要：We have used Mossbauer emission spectroscopy to study an oxygenated heme complex, produced in a frozen solution by nuclear decay from the isomorphous 57Co-labeled compound. The Mossbauer parameters agree with those obtained by Mossbauer absorption spectroscopy of oxyhemoglobin. Thus, a nonprotein environment for iron can duplicate the unique oxyhemoglobin Mossbauer spectrum. The electronic structure of the heme iron in oxyhemoglobin is not significantly influenced by the protein environment. Mossbauer emission spectroscopy can be useful in the investigation of heme proteins.
