Des molécules de LiI, KI et CsI sont isolées dans une matrice d'argon solide a 4,2 K et des études d'effet Mössbauer 129I sont effectuées. Le spectre observé révèle de larges raies d'absorption, avec une largeur décroissante de LiI à CsI. L'élargissement des raies d'absorption est attribué à une interaction quadrupolaire. Le spectre d'échantillons cristallins de ces mêmes matériaux sont aussi relevés. La comparaison entre des déplacements isomériques dans les cristaux et les molécules conduit à la nature des liaisons chimiques dans les halogénures alcalins. L'origine du gradient du champ électrique et les distances intramoléculaires dans la matrice d'argon sont étudiées.Molecules of LiI, KI and CsI were isolated in a solid argon matrix at 4...
