Description

Resume.- L'application des spectres Mossbauer a I'etude de I'etat des atomes de fer dans les molecules biologiques est decrite. Le dkplacement chirnique, quand i l est bien calibre, permet de determiner l'etat d'oxydation du fer. Le couplage rnagnetique hyperfin est m&me plus sensible a I'etat du fer et, pour les proteines fer-soufre, fournit une preuve directe que les groupes d'atomes de fer sont fortement couples a~itiferromagnetiquement. Abstract.-The application of Mossbauer spectra to the study of the state of iron atoms in biological ~nolecules is described. The chetiiical shift when suitably calibrated enables the oxidation state of the iron to be determined. The magnetic hyperfine coupling is even more sensitive to the state of the iron and for iron-sulphur proteins provides direct evidence that groups of iron atoms are strongly coupled together antiferrornagtietically. 1.
