NMR frequency-sweep spectrometer 6.3 T 

 

NMR frequency-sweep spectrometer in a magnetic field 6.3 T. All spectrometer components are broad-banded except the probe head, which is automatically tuned via a stepper motor system. This spectrometer is dedicated to NMR spectroscopy of very broad absorption lines up to 12 MHz (suitable for NMR of quasicrystals, metallic glasses, nanomagnets, disordered solids, etc...).
