NMR

The NMR facilities at IRCELYON includes 2 spectrometers: one dedicated to characterization of solids and non-soluble materials by solid state NMR, and the second one adapted for high resolution analysis of liquid samples.
NMR spectroscopy is a key analytical technique for structure elucidation of a wide range of materials from small molecules to macromolecule compounds. The technique provides detailed molecular information that allows researchers have in-depth understanding of composition, chemical structure, morphology, and dynamics.
Solid state NMR provides information of local order, crystallinity, crystallographic sites, and connectivity or molecular dynamic. Solid state NMR at ircelyon is more specifically dedicated to catalysts, inorganic or porous materials characterization. Projects come from a wide variety of fields including biomass, catalysts, polymer or MOF materials, organometallics, and inorganics.
The NMR facilities is part of the platform for Catalytic Materials Characterization from IRCELYON. Equipments are open to academic as well as industrial researcher in form of collaborations and service agreements.
