Solid-State Nuclear Magnetic Resonance

Introduction

Solid-state Nuclear Magnetic Resonance is a non-destructive technique for locally probing the structure of materials.

The principle of solid NMR is identical to that of liquid NMR: in an intense magnetic field, the application of a radiofrequency electromagnetic field will cause a disturbance of the equilibrium state of the spins of the nuclei. The return to equilibrium of these solicited nuclei will generate the NMR response. But unlike the liquid state, the interactions governing this return to equilibrium are no longer averaged by the isotropic nature of the material. This makes solid-state NMR a powerfull local probe for studying the nanoscale of matter.

The two solid-state NMR spectrometers (Bruker AVIII 300 & Bruker AVIII 600) recieve joint financial support from the ISCR (70%) and the Institut de Physique de Rennes (IPR - 30%). All spectrometers, probeheads and specific facilities were co-funded by EU.
