Le complexe hexaquo-ferrique [Fe(H2O)6]3+ a été étudié par spectroscopie Mössbauer sous forme d'une solution aqueuse, diluée magnétiquement, et congelée en un état vitreux homogène. Les spectres sont enregistrés à 4,5 K sous champs magnétiques allant jusqu'à 6 200 G. Ils montrent une structure hyperfine paramagnétique, bien résolue. En présence des champs magnétiques faibles les raies ont une forme anormale, non symétrique. En comparant les spectres obtenus en champs faibles et forts on conclut, que la forme anormale des raies n'est pas, comme on le pensait, due à l'orientation au hasard des axes du champ cristallin, par rapport à la direction du champ appliqué. La forme des raies est attribuée aux variations des paramètres du champ cristal...
