Enhanced Solid-State Nuclear Magnetic Resonance

Résumé des résultats (Abstract) (Allemand)

This proposal aims at optimising a novel apparatus for solid-state nuclear magnetic resonance (NMR) that yields signal enhancement by up to two orders of magnitude through the use of dynamic nuclear polarisation (DNP). The methods for enhancing nuclear polarisation by irradiation of electronic transitions will be coupled with state-of-the-art NMR techniques, using very fast spinning of the samples and very intense radio-frequency fields. We shall test and improve the instrumentation recently developed by Bruker, the sample preparation protocol, and methods for obtaining enhanced spectra of various materials. The development of the instrumention and applications will take place on a DNP-NMR platform that will be set up at the EPFL.
