C.Bessada, A.L.Rollet, A.Rakhmatullin,I.Nuta, P.Florian, D.Massiot, 'In situ NMR approach of the local structure of molten materials at high temperature', C. R. Chim. 9 374-380 (2006) doi:10.1016/j.crci.2005.06.007
The developments of NMR spectroscopy at high temperature now allow us to study in situ a great number of molten materials. This technique is sensitive to local environment around the nucleus, and gives selective and quantitative information not limited by the disorder existing in liquids. NMR can thus provide a microscopic approach of the structure and dynamics of molten compounds by means of knowledge of different species existing in the melt, the average coordination, or nature of the first neighbors. We present high temperature NMR approach of molten fluoride systems of nuclear interest and description of the local structure around each nucleus, and its evolution with the composition.
