Abstract

The present invention concerns an apparatus (1′) for NMR spectroscopy and/or NMR imaging of a sample. The apparatus comprises a static probe comprising an outer coil for excitation of nuclei of the sample by generating an incident radio frequency field at the Larmor frequency of the nuclei, and for reception of a return radio frequency field emitted by the sample, and a sensitive inner coil (6a′) which is mounted closely around or in contact with the sample container and which is wirelessly coupled to the outer coil by an electromagnetic radio frequency field. The sensitive inner coil is embedded in an inner spinning rotor (2) which is rotatively mounted inside the static probe and which is integral with the sample container, so that the filling factor and the radio frequency field amplitude in the sensitive coil are maximized.
